Representative sensors among various sensors that may be included in the sensing unit 140 will be described in more detail.

First, the proximity sensor 141 refers to a sensor that detects the presence of an object approaching a predetermined detection surface, or the presence of an object in the vicinity of the detection surface, without mechanical contact by using electromagnetic force or infrared rays. The proximity sensor 141 may be disposed in the inner area of the mobile terminal or in proximity to the touch screen, which is covered by the touch screen.

In the case where the touch screen is electrostatic, the proximity sensor 141 can be configured to detect the proximity of the object with a change of the electric field along the proximity of the object having conductivity. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

On the other hand, for convenience of explanation, the act of recognizing that the object is located on the touch screen in proximity with no object touching the touch screen is referred to as "proximity touch & The act of actually touching an object on the screen is called a "contact touch. &Quot; The position at which the object is closely touched on the touch screen means a position where the object corresponds to the touch screen vertically when the object is touched. The proximity sensor 141 can detect a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, have.

Here, the touch object may be a finger, a touch pen, a stylus pen, a pointer, or the like as an object to which a touch is applied to the touch sensor.

Thus, when there is a touch input to the touch sensor, the corresponding signal (s) is sent to the touch controller. The touch controller processes the signal (s) and transmits the corresponding data to the controller 180. Thus, the control unit 180 can know which area of the display unit 151 is touched or the like. Here, the touch controller may be a separate component from the control unit 180, and may be the control unit 180 itself.

Meanwhile, the controller 180 can calculate the position of the wave generating source through the information sensed by the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the fact that the light is much faster than the ultrasonic wave, that is, the time when the light reaches the optical sensor is much faster than the time the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generating source can be calculated using the time difference with the time when the ultrasonic wave reaches the reference signal.

An antenna provided on the upper portion of the mobile terminal may be referred to as an upper antenna 130a and an antenna provided on the lower portion may be referred to as a lower antenna 130b. In addition, the plurality of antenna devices 130 may be disposed at each end of the terminal, and each antenna device may be configured to transmit and receive radio signals of different frequency bands.

The frame 155 may be formed of a metal material so that sufficient rigidity can be maintained even if the frame 155 is formed to have a small thickness. The metal frame 155 may be operated as a ground. That is, the circuit board 181 or the antenna device can be grounded to the frame 155, and the frame 155 can operate as the circuit board 181 or the ground of the antenna device. In this case, the frame 155 may extend the ground of the mobile terminal.

The circuit board 181 is electrically connected to the antenna device and is configured to process a radio signal (or radio electromagnetic wave) transmitted and received by the antenna device. For processing of the radio signals, a plurality of transceiver circuits 138 may be formed or mounted on the circuit board 181.

The transceiver circuits may be formed including one or more integrated circuits and associated electrical components. In one example, the transceiver circuit may include a transmit integrated circuit, a receive integrated circuit, a switching circuit, an amplifier, and the like, and may be termed a radio frequency integrated circuit (RFIC).

A plurality of transceiver circuits simultaneously feed conductive members that are radiators, so that a plurality of antenna devices can operate simultaneously. For example, while either one is transmitting, the other can receive, both transmit or both receive.

The RFIC 138 may also be configured to implement a control algorithm that controls the use of the antenna in the antenna device. For example, to support antenna diversity schemes and MIMO schemes or other multi-antenna schemes, the RFIC 138 may perform signal quality monitoring operations, sensor monitoring operations, and other data gathering operations, Accordingly, it is possible to control which antenna structure is used to receive and process the data. As an example, the RFIC 138 may control which of two or more antennas may be used to receive an incoming radio frequency signal, and may control which of two or more antennas is used to transmit the radio frequency signal , And the processing of routing data streams in parallel via two or more antennas.

In one example, the coaxial cables 144 and 145 may be connected to a feeder that feeds the antenna devices. The power supply devices may be formed on one surface of a flexible circuit board 181a formed to process signals input from the operation unit 123a. The other surface of the flexible circuit board 181a may be combined with a signal transmission unit 123c formed to transmit a signal of the operation unit 217. [ In this case, a dome may be formed on the other surface of the flexible circuit board 181a, and an actuator may be formed in the signal transmission unit 123c.

An embodiment of the present invention is to solve the problem that the quality of wireless communication is degraded by the user's body. Hereinafter, a hand grip issue generated when a user grips the mobile terminal 100 by hand Contents for improvement are disclosed.

2A and 2B illustrate a state in which a user grasps and uses the mobile terminal 100. FIG. 2A illustrates a state in which both ends of the mobile terminal 100 are held with both hands while the mobile terminal 100 is disposed horizontally And FIG. 2B illustrates a state in which the mobile terminal 100 is held vertically and the mobile terminal 100 is wrapped around the rear face thereof. The radiator of the upper antenna 130a formed on the upper portion of the mobile terminal 100 may be an upper frame 111 forming the upper end surface of the mobile terminal 100, The radiator of the lower antenna 130b may be the lower frame 112 forming the lower end surface of the mobile terminal 100. [ At this time, the upper antenna 130a is fed by the feeder 131u and the lower antenna 130b is fed by the feeder 131.

The radiators of the upper antenna 130a and the lower antenna 130b may be metal frames 111 and 112 forming the side surface of the mobile terminal 100 and metal covers 111 and 112 covering the rear surface of the mobile terminal 100 102).

In this way, the user often uses the mobile terminal 100 in a state of wrapping the upper and / or lower ends of the mobile terminal 100, which is a bezel portion of the mobile terminal 100 when using the mobile terminal 100. [ The antenna devices 130, 130a and 130b for wireless communication are mainly disposed at the edge of the mobile terminal 100 to improve the radiation efficiency. The antenna devices 130, 130a, Wrapping the area reduces radiation efficiency.

3A and 3B are diagrams for explaining the arrangement of the transmitting and receiving antenna apparatuses 130a and 130b for wireless communication of the mobile terminal 100. FIG 3A is a block diagram illustrating a transmitter And an antenna device 130b for a receiver circuit RX and a receiving antenna device 130a are disposed at an upper end of the mobile terminal 100. [ As described above, when both the antenna device 130b for transmitting and receiving are fixedly disposed in the lower portion of the mobile terminal 100, a death grip phenomenon may occur due to the user's body. That is, a hand effect phenomenon occurs in which the radiation performance is hindered by the user's hand. In order to solve this problem, if the antenna device 130a including the transmitter circuit RX and the receiver circuit TX is moved to the upper portion of the mobile terminal 100 as shown in FIG. 3B, the hand effect phenomenon can be mitigated However, the problem of Specific Absorption Rate (SAR) remains.

In particular, in the case of radiation for transmission, if the radiation performance of the antenna device 130a is excellent, power may not be large. However, if the radiation performance of the antenna device 130a is low, the same radio communication quality can be realized only by increasing the power . That is, in order to improve the quality of wireless communication with a small power, the radiation performance of the antenna device 130a must be improved.

In order to solve the above-described problems, the mobile terminal 100 according to an embodiment of the present invention includes a feeding antenna (not shown) for changing the radiation direction or radiation region of the radiator according to a state in which the user holds the mobile terminal 100 ).

The antenna device according to an embodiment of the present invention relates to a technique for changing the radiation pattern such as the radiation direction or the radiation area of the radiator by changing the feeding position to suppress the antenna performance deterioration by the user.

FIG. 4A is a conceptual diagram of an antenna device 130 according to an embodiment of the present invention, and FIGS. 5A and 5B are views for explaining a state in which the antenna device 130 of FIG. 4A is applied.

4A and FIG. 5B, the mobile terminal 100 according to an embodiment of the present invention includes a terminal body, a metal case forming an outer surface of the terminal body, and at least a part of which is a radiator of the antenna device 130, (112), a feed part (131) for feeding the metal case (112), and a feeding part (131) disposed between the metal case (112) and the feed part (131) A transmission line 132 and a first and a second switches 133a and 133b.

1D, the power feeder 131 may be powered by coaxial cables 144 and 145 connected to the transmission / reception circuit 138, for example.

The radiator of the antenna device 130 is a metal case 112 which forms an outer appearance of the mobile terminal 100. However, the present invention is not limited thereto. For example, when feeding swap is required by the feeding part, the description of the embodiment of the present invention can be applied.

The metal case 112 may be a lower frame 112 forming a lower side surface of the mobile terminal 100. The first switch 133a is connected to one side of the transmission line 132 and is formed adjacent to one end of the radiator that is the metal case 112 to electrically connect the transmission line 132 and the radiator. The second switch 133b is connected to the other end of the transmission line 132 and is formed adjacent to the other end of the radiator to electrically connect the transmission line 132 and the radiator 112. [ At this time, the path L1 formed by the current formed via the first switch 133a is substantially L-shaped, and the path L2 formed by the current formed via the second switch 133b is an inverted L shape to be.

In addition, a gap structure may be provided in a part of the metal case 112. For example, the metal case 112 may be provided with one or more gaps. These gaps may be filled with a dielectric such as polymer, ceramic, glass, or the like. The gap may separate the metal case 112 into one or more peripheral conductive member segments. For example, two segments of the metal case 112, three segments of the metal case 112 if there are three gaps, four segments of the metal case 112 if there are four gaps, There can be segments. The segments of the metal case 112 formed in this manner may form part of the antenna.

At this time, the first and second switches 133a and 133b are selectively operated to vary the radiation region of the radiator. Thereby, the two paths L1 and L2 are not simultaneously formed but only one of them is formed. The branch switch 134 controls this.

Whether to operate the first and second switches 133a and 133b is determined by the RFIC 138. For example, when the current is supplied to the first switch 133a and the radiation by the path L1 is inhibited, a current is automatically supplied to the second switch 133b so that the current is directly supplied to the path L2 by the path L2 Allow radiation to occur. Control of these functions is performed in the RFIC 138. That is, the RFIC 138 performs a kind of controller function.

More specifically, the RFIC 138 may be used to implement an antenna diversity scheme. Such a diversity scheme may support receiver diversity and / or transmitter diversity. For example, the RFIC 138 may include multiple receivers, each associated with each antenna, or may be used to route signals from each of those antennas (e.g., using a time multiplexed arrangement) to a shared receiver Lt; / RTI > The receiver diversity can be implemented such that a receiver that receives the best antenna signal is used. A switching circuit may be included to allow the antenna to swap in real time. For example, if a particular antenna is determined to be disconnected during a signal transmission operation, the switching circuit may be used to connect the active transmitter circuitry within the device to an unblocked antenna.

If the current is flowed only to the first switch 133a by the branching switch 134 and the flow of current is blocked by the second switch 133b, the path L1 will be formed. 4A and FIG. 5A). On the other hand, when the current flows to the first switch 133a by the branching switch 134 and the current flows only through the second switch 133b, the path L2 is formed The maximum emission point of the path L1 is the right end of the lower frame 112 in FIG. 4A and the maximum emission point of the path L2 is in the lower frame (FIG. 4A) 112). At this time, the first and second matching units 135a and 135b may be disposed between the branch switch 134 and the first and second switches 133a and 133b, respectively.

The distance D1 between the first switch 133a and the other end of the radiator 112 must be equal to the distance between the first switch 133a and the other end of the radiator 112, The distance D2 from the first end 133b to the first end of the radiator 112 should be the same.

The other end of the radiator 112 refers to a portion of both ends of the radiator 112 adjacent to the second switch 133b and one end of the radiator 112 corresponds to the amount of the radiator 112 Means a portion of the end portion adjacent to the first switch 133a. The same D1 and D2 are meant to mean that the electrical distances are the same, including that the physical distances are the same. The electrical length at this time means the electrical length of the radiator that operates with the antenna and the physical distance D1 from the feeder 131 to the other end of the radiator 112 via the first switch 133a, And the physical distance D2 from the feeder 131 to the one end of the radiator 112 via the second switch 133b do not necessarily have to be the same and the two electrical distances are the same .

An electrical device for matching electrical lengths may be disposed on the transmission line 132. The electrical length is a length that can be converted into a length of a wavelength unit, and may be changed depending on a path of a current, a resistance, and the like. The resistance at this time can be varied by a combination of lumped elements such as an inductor, a capacitor, and the like.

5A shows a state in which the first switch 133a is turned on and the second switch 133b is turned off. Referring to FIG. 5a, when the first switch 133a is turned on, The current flows through the first switch 133a and the metal case 112 to the right in Fig. 5A. Since the second switch 133b is cut off, the main radiation region by the radiator 112 is the A region adjacent to the end of the radiator. If the user holds the right side in FIG. 5A, the radiation performance is lowered by the user's body do.

5B shows a state in which the first switch 133a is off and the second switch 133b is on. Referring to FIG. 5b, the current supplied by the feeder 131 is supplied to the transmission line Flows toward the end of the metal case 112 adjacent to the first switch 133a via the first switch 132, the second switch 133b and the metal case 112. [ A radiation pattern is formed around the metal case 112 in the form of B by the current flow. In this case, there is no significant influence on the radiation efficiency by the user's body.

Thus, by using the same radiator and changing the radiation pattern (or radiation area), it is possible to suppress the phenomenon of the death grip by the user.

5A and 5B, when a part of a user's body part surrounds the mobile terminal 100 and hinders the radiation performance of the antenna device 130, the same resonance frequency So that the performance of the antenna device 130 due to the user's body can be suppressed by changing the radiation direction or the radiation area. That is, the flow of current can be automatically changed by the branch switch 134 so that the main radiation is performed through one end or the other end of the metal case 112 as the radiator in FIG. 5A.

5A, when the radiation performance of the radiator 112 is impeded, the radiation performance of the antenna apparatus 130b is deteriorated by changing the main radiation region of the radiator 112 as shown in FIG. 5B . For this purpose, the resonance frequency emitted in FIG. 5A and the resonance frequency emitted in FIG. 5B should be the same or similar.

As described above, the flow of the current passing through the first switch 133a and the flow of the current passing through the second switch 133b are not generated at the same time but are selectively generated. For this purpose, a branching switch 134 is formed at a portion connecting the feeder 131 and the transmission line 132. The branching switch 134 is provided between the feeder 131 and the transmission line 132 and selectively connects the currents to the first and second switches 133a and 133b. The branch switch 134 is formed on at least one of both ends of the transmission line 132. That is, there may be only one branch switch 134 or two branch switches 134, but in either case, the electrical lengths of currents formed at both ends of the radiator 112 in the feeder 131 should be the same.

If the feeder 131 is one and the branching switch 134 is one, as shown in FIG. 4A, the feeder 131 may be formed independently of the first switch 133a, The feeder 131 may be formed independently of the second switch 133b.

4B shows that the branching switch 134 is formed inside the transmission / reception circuit 138. In this case, the power feeding part 131 is formed in two and is adjacent to the first switch 133a And a second power feeder 131b formed adjacent to the second switch 133b.

Also, the branch switch 134 must also have two. 4B, the branching switch 134 is connected to the first feeding part 131a to control the flow of the current to the first switch 133a, (131b) to control the flow of current to the second switch (133b). The branching switch 134 is not formed inside the transmission / reception circuit 138, but may be connected to the transmission / reception circuit 138.

At this time, when current is supplied to the metal case 112 via the first switch 133a, the current is supplied to the first switch 133a by the branching switch 134, and at the same time, And the second switch 133b is in an off state. When a current is supplied to the metal case 112 via the second switch 133b, the current is supplied to the second switch 133b by the branching switch 134, and at the same time, the second switch 133b The first switch 133a is in the on state and the first switch 133a is in the off state. As described above, according to the embodiment of the present invention, the supply of current through the first and second switches 133a and 133b is selectively performed, thereby preventing the isolation problem from occurring.

At this time, the flow of the current through the first switch 133a is formed along the path L1 as in the case of FIG. 4A, and the flow of the current through the second switch 133b is formed along the path L2 do. The electrical lengths of the two paths L1 and L2 are the same.

4B, when the branching switch 134 is used, the transmission line 132 is unnecessary.

The first and second switches 133a and 133b may be a single pole single throw (SPST) switch and may be a contact relay switch. The third and fourth switches 134a and 134b may be a single pole double throw) can be a changeover relay.

The feeder 131 for applying a signal to the metal case 112 is branched at most near the metal case 112 through the branch switch 134a. Further, in order to make the electric lengths of the currents along the two paths L1 and L2 equal or similar to each other, the feeding part 131 of the metal case 112 is symmetrically connected to the connection part connected to the metal case 112 .

Generally, in order to minimize performance degradation due to hand grip, matching efficiency is compensated by using a tuner for matching. In an embodiment of the present invention, performance degradation due to hand grip is minimized So that the radiation efficiency can be compensated for by using the beam forming phenomenon caused by changing the position of the power feeder 131.

In general, the position of the feeding part 131 is generally a lambda / 4 position of a low band. In an embodiment of the present invention, the positions where the first and second feeding parts 131a and 131b are formed are symmetrical . Since the metal case 112, which is generally exposed to the outside, is symmetrically positioned on both sides of the USB terminal (see the socket 119 of FIG. 1), either the ring type or the metal cover type May be used as a low band, and the other may be used as a mid band or a high band (Mid or High Band).
