Omnidirectional radiation wireless communication transmitting device and wireless communication electronic device using same

field of invention

The present invention relates to a wireless communication technology, in particular to a wireless communication radio wave transmitting device with an omnidirectional radiation field and a wireless communication electronic device using it, which can be adapted to be matched with a portable On a wireless communication device, such as a notebook computer equipped with a wireless network card, a wireless network access point (wireless network access point), or a mobile phone, etc., the wireless signal generated by the wireless communication device is used along a It can be emitted on a predetermined propagation plane; and when the placement state of the wireless communication device and the wireless communication electronic device is changed, the radio waves emitted by it can be kept roughly on the original predetermined propagation plane, and There will be no receiving dead angle.

Background of the invention

Antenna is a key component of wireless communication equipment, and its radiation pattern points to the quality of communication of Youguan. If the antenna is fixed and the transmission object is in a fixed direction, the field pattern pointing of the antenna can be designed to be a fixed direction. For example, the ground antenna used for satellite communication is a fixed field pattern pointing. However, the current portable wireless communication equipment, such as notebook computers, mobile phones, etc., the radio waves emitted by them must be omnidirectional in the horizontal direction, so that unspecified objects in all directions can receive them. Send message.

The current wireless network transmission standard is the most mature wireless network transmission protocol stipulated by the IEEE 802.11b standard. This standard wireless network card has two antennas, including a main antenna (MAIN) and an auxiliary antenna (AUX). When receiving radio waves, a high-frequency switcher (RFSWITCH) is used to switch the two antennas; that is, if the intensity of the radio waves received by the main antenna is relatively high, the high-frequency switcher will select the main antenna as the receiving antenna; Conversely, if the intensity of radio waves received by the auxiliary antenna is relatively high, the high-frequency switch will select the auxiliary antenna as the receiving antenna. However, when transmitting radio waves, since the location of the receiving object is unknown, it is impossible to know in advance which one of the main antenna or the auxiliary antenna can make the receiving object have a better receiving effect. Therefore, when transmitting radio waves, the IEEE 802.11b standard wireless network card is fixed with the main antenna as the transmitting antenna.

In addition, Bluetooth is another wireless network transmission protocol commonly used at present. This standard wireless network card has only one main antenna (MIAN), which is used as a receiving antenna and a transmitting antenna at the same time.

However, one of the disadvantages of the above-mentioned traditional radio wave transmitting device for wireless communication is that when the placement state of the transmitting antenna is changed, the field direction of the radio wave emitted by it will be changed, thus causing Receive dead ends.

Taking a notebook computer as an example, the transmitting antenna is generally set on the display screen panel, and is pre-designed so that when the display screen panel is in the open state, the radiation pattern emitted by the electric wave is omnidirectional radiation in the horizontal direction. field type. But when the user closes the display screen panel, since the placement state of the antenna will rotate 90 degrees with the display screen panel, the field direction of its electric wave emission will be changed to a vertical omnidirectional Field pattern, so in some orientations in the horizontal direction, there is a receiving dead angle. 1 and 2 of the accompanying drawings, the shortcomings of this conventional technology are briefly described in a diagrammatic manner.

Fig. 1 is a schematic perspective view, which shows a typical notebook computer 100, which has a main body 101 and a rotatable display screen panel 102, and it is also equipped with a wireless network card 103, such as an IEEE 802.11b Or bluetooth standard wireless network card (note: the following drawings are simplified schematic drawings, which only show the elements related to the present invention; the rest of the non-related elements are omitted; and the shown elements are not based on the actual configuration position and size ratio drawing). In addition, the space where the notebook computer 100 is located will be described with three-dimensional rectangular coordinates (X, Y, Z), wherein the horizontal plane is represented by the X-Y plane; and it is assumed that the display screen panel 102 is approximately parallel to the X-Y plane when it is closed. ; and when it is turned on, it is roughly placed on the Y-Z plane.

The above-mentioned wireless network card 103 uses a planar radiation field antenna 110 to convert the information generated by the wireless network card 103 into radio waves, that is, its radiation pattern is emitted in various directions of a specific propagation plane. . The antenna 110 is disposed on one side of the display screen panel 102, and its configuration is such that when the display screen panel 102 is in an open state, the radiation field pattern EM emitted by it can be the X-Y plane of the three-dimensional rectangular coordinates As shown in FIG. 1( a ), it is the radiation pattern of the antenna 110 in FIG. 1 , which is nearly circular and suitable for unspecified directions.

However, as shown in FIG. 2 , when the display screen panel 102 is in the closed state, the above-mentioned antenna configuration will make the radiation field pattern EM emitted by the antenna 110 change to various directions of the Y-Z plane, resulting in only reception in the Y-axis direction. The object can receive the radio waves emitted by the antenna 110, but the receiving object in the X-axis direction is difficult to receive, as shown in Figure 2(a), which is the radiation pattern of the antenna 110 in Figure 2, point A in the figure , B is the receiving dead angle in the X-axis direction.

In addition to the above-mentioned notebook computer, antennas on wireless network access devices and mobile phones also have the above-mentioned problems.

Summary of the invention

In view of the above-mentioned shortcomings of the traditional technology, the main purpose of the present invention is to provide a wireless communication radio wave transmitter with an omnidirectional radiation field and a wireless communication electronic device using it. The wireless communication radio wave transmitter can be used in When the placement state of the matched wireless communication device is changed, the radio waves emitted by it still have an omnidirectional radiation pattern.

According to the above-mentioned purpose, the present invention provides a novel radio wave transmitting device for wireless communication.

The radio wave transmitting device for wireless communication of the present invention is suitable for matching with a wireless communication device, such as a notebook computer, a wireless network access device, or a mobile phone, to use the wireless signal generated by the wireless communication device It is emitted by radio waves; and when the placement of the wireless communication device is changed, the emitted radiation field is still roughly in the shape of a graph, without generating a dead angle for reception.

The first antenna 210 is arranged on one side of the display screen panel 202, and its configuration is such that when the display screen panel 202 is turned on, the radiation field pattern EM emitted by it is each of the X-Y planes of the three-dimensional rectangular coordinates. It is emitted in different directions (that is, it is emitted in all directions in the horizontal direction). However, when the display screen panel 202 is closed in this antenna configuration, the radiation pattern emitted by the first antenna 210 will change to various directions of the Y-Z plane.

The second antenna 220 is also a planar field antenna, and it is configured on the top edge of the display screen panel 202, and its configuration is such that when the display screen panel 202 is closed, the emitted radiation field is All orientations of the X-Y plane.

In this embodiment, when the display screen panel 202 is in the open state, the push switch 231' is in the unpressed state, so that a first switching state is formed inside it, which is used to switch the output terminal of the wireless network card 203 connected to the first antenna 210; and when the display screen panel 202 is closed, it will drive the protruding pin 232' to push the push switch 231' downward, thus causing the push switch 231' to form a second switching state, It is used to connect the output end of the wireless network card 203 to the second antenna 220 .

In addition, as shown in FIG. 7 , the second implementation of the touch switch unit 230 (represented by the symbol 230 ″ here) includes a mechanical push switch 231 ″ and a protruding tip 232 ″; wherein the mechanical push switch 231 "is arranged in the main body 201 of the notebook computer and is located below the rotating shaft 202a of the liquid crystal display screen 202, and the protrusion 232" is arranged on the rotating shaft 202a. In this embodiment, when the display screen panel 202 is in an open state , the push switch 231" will not be pressed by the protruding tip 232", so a first switching state is formed inside it to connect the output end of the wireless network card 203 to the first antenna 210; and on the display screen panel When the 202 is closed, the rotating shaft 202a will drive the protruding pin 232 ″ to rotate and push the push switch 231 ″, thus causing the push switch 231 ″ to form a second switching state, which is used to switch the output of the wireless network card 203 connected to the second antenna 220.

In addition, as shown in FIG. 8, the third implementation of the touch switch unit 230 (represented by the label 230'" here) includes an electronic sleep state detection device 231'" and a micro switch 232'"; Wherein the sleep state detecting device 231 ′″ is coupled to the built-in sleep device 204 of the notebook computer 200 to detect whether the sleep device 204 has been activated. Generally speaking, the sleep device 204 of the notebook computer 200 is designed to be activated when the display screen panel 202 is closed. Therefore, the sleep state detection device 231'" is designed to set the microswitch 232'" to the first switching state when detecting that the built-in sleep device 204 in the notebook computer 200 is not activated, for The output end of the wireless network card 203 is connected to the first antenna 210; and when it is detected that the sleep device 204 is activated, the micro switch 232'" is set to the second switching state for the wireless network card 203 The output terminal of is connected to the second antenna 220.

Please refer to FIG. 9, when the user closes the display screen panel 202, it will cause the aforesaid touch switch unit 230 to switch the wireless signal output by the wireless network card 203 from the first antenna 210 to the second antenna 220, The wireless signal generated by the wireless network card 203 is now transmitted through the second antenna 220 instead. Since the second antenna 220 is configured such that when the display screen panel 202 is closed, the radiation field EM emitted by it is in various directions of the X-Y plane, so there is no receiving dead angle in the Y-axis direction as in the conventional technology.
