Fig. 2 shows a schematic diagram of an integration module 200 according to an embodiment of the invention. In the embodiment of fig. 2, the integrating module 200 includes a Filter Circuit 270, a proximity Sensor (Proximity Sensor, also called "P-Sensor") 280, and a Tuning Circuit 290. The internal structures of the filter circuit 270 and the adjusting circuit 290 are not particularly limited in the present invention, and may be adjusted according to different requirements. For example, each of the filter circuit 270 and the adjustment circuit 290 may each include one or more inductors (Inductor), one or more capacitors (capacitors), and one or more resistors (resistors). The third radiating portion 180 may also be coupled to a proximity sensor 280 via a filter circuit 270, wherein the filter circuit 270 may also be coupled to a ground potential VSS via an adjusting circuit 290. Generally, the third radiating portion 180 may serve as an associated sensing board (SENSING PAD) of the proximity sensor 280, and the filter circuit 270 may be used to prevent the presence of the proximity sensor 280 from negatively affecting the radiation performance of the hybrid antenna structure 100. In addition, the adjustment circuit 290 is added to help increase the operation bandwidth of the hybrid antenna structure 100.
In detail, the filter circuit 270 includes a first inductor LA, a second inductor LB, a capacitor C1, and a resistor R1, and the adjusting circuit 290 includes a Short-circuit path (Short-Circuited Path) 291, a capacitance path (CAPACITIVE PATH) 292, a Open-circuit path (Open-Circuited Path) 293, an inductance path (InductivePath) 294, and a switch (SWITCH ELEMENT) 295.
The capacitor C1 has a first end and a second end, wherein the first end of the capacitor C1 is coupled to a first node N1, and the second end of the capacitor C1 is coupled to a second node N2. The first node N1 may also be coupled to a first end 181 of the third radiating portion 180. The first inductor LA has a first end and a second end, wherein the first end of the first inductor LA is coupled to the second node N2, and the second end of the first inductor LA is coupled to the ground potential VSS. The second inductor LB has a first end and a second end, wherein the first end of the second inductor LB is coupled to a third node N3, and the second end of the second inductor LB is coupled to the first node N1. The resistor R1 has a first end and a second end, wherein the first end of the resistor R1 is coupled to the third node N3, and the second end of the resistor R1 is coupled to the proximity sensor 280.
In the filter circuit 270, the capacitor C1 can be used as a High-pass filter (High-PASS FILTER ELEMENT) to prevent Low-Frequency Noise (Low-Frequency Noise) from entering the adjustment circuit 290. According to the actual measurement result, the addition of the first inductor LA can reduce the probability of malfunction of the proximity sensor 280 when the adjustment circuit 290 is switched. The second inductor LB may act as a Low pass filter (Low-PASS FILTER ELEMENT) that may prevent the proximity sensor 280 from adversely affecting the radiation performance of the hybrid antenna structure 100. In addition, the resistor R1 can be used to reduce the interference between the proximity sensor 280 and the remaining radiation portion.
The shorting path 291, the capacitive path 292, the breaking path 293, and the inductive path 294 may be respectively coupled to the ground potential VSS of the ground element 110. One end of the switch 295 is coupled to the second node N2, and the other end of the switch 295 can switch among the short circuit path 291, the capacitor path 292, the open circuit path 293, and the inductor path 294 according to a control signal SC. Thus, the second node N2 will be coupled to the ground potential VSS via a path selected by the switch 295. For example, the control signal SC may be generated by a Processor (not shown) based on a user input, but is not limited thereto.
When the switch 295 switches among the short circuit path 291, the capacitor path 292, the open circuit path 293, and the inductor path 294, a ground impedance value of the hybrid antenna structure 100 can be adjusted accordingly. Based on the actual measurement results, this design helps to greatly increase the operation bandwidth of the hybrid antenna structure 100, especially the first frequency band and the second frequency band.
In some embodiments, the element parameters of the hybrid antenna structure 100 may be as follows. The Inductance value (Inductance) of the first inductor LA may be greater than or equal to 56nH. The inductance value of the second inductor LB may be greater than or equal to 56nH. The Capacitance value (Capacitance) of the capacitor C1 may be between 10pF and 180 pF. The Resistance value (Resistance) of the resistor R1 may be between 0Ω and 10kΩ. The capacitance value of the capacitive path 292 may be between 1pF and 47 pF. The inductance value of the inductance path 294 may be between 10nH and 56nH. The above parameter ranges are determined based on a number of experimental results, which help minimize the influence of the proximity sensor 280 and optimize the radiation performance of the hybrid antenna structure 100.
Fig. 3 shows a schematic diagram of an integration module 300 according to another embodiment of the invention. Fig. 3 is similar to fig. 2. In the embodiment of fig. 3, a filter circuit 370 of the integration module 300 does not include the aforementioned resistor R1, but further includes a third inductor LC. In detail, the third inductor LC has a first end and a second end, wherein the first end of the third inductor LC is coupled to the third node N3, and the second end of the third inductor LC is coupled to the proximity sensor 280. For example, the inductance value of the third inductor LC may be between 10nH and 330nH, but is not limited thereto. Based on the actual measurement, the third inductor LC may also be used to reduce the interference between the proximity sensor 280 and the remaining radiating portion. The remaining features of the integration module 300 of fig. 3 are similar to those of the integration module 200 of fig. 2, so that similar operation effects can be achieved in both embodiments.
Fig. 4 shows a perspective view of a hybrid antenna structure 400 according to an embodiment of the invention. Fig. 4 is similar to fig. 1. In the embodiment of fig. 4, the hybrid antenna structure 400 includes a grounding element (not shown), a non-conductive supporting element (Nonconductive Support Element), a feeding radiating portion 420, a first radiating portion 430, a second radiating portion 440, a first connecting radiating portion 450, a second connecting radiating portion 460, a short-circuit radiating portion 470, a third radiating portion 480, a signal source 490, and an integrating module (not shown), wherein the feeding radiating portion 420, the second radiating portion 440, the short-circuit radiating portion 470, and the third radiating portion 480 are all distributed on the non-conductive supporting element 405. In some embodiments, the shorting radiating portion 470 and the third radiating portion 480 may be disposed on different surfaces of the non-conductor support element 405.
For example, the non-conductive support element 405 may be implemented by a Holder or a printed circuit board (Printed Circuit Board, PCB), and the first radiating portion 430 may be implemented by a ferrous Part or a stamped element (STAMPING ELEMENT). The second radiating portion 440 may be printed on a surface of the non-conductor support element 405. Thus, both the first radiating portion 430 and the second radiating portion 440 may lie substantially on different planes that are parallel to each other. In addition, the first connection radiating portion 450 and the second connection radiating portion 460 may be implemented by a Pin (Pogo Pin) or a metal spring plate (METAL SPRING). However, the present invention is not limited thereto. In other embodiments, the first radiating portion 430, the first connecting radiating portion 450, and the second connecting radiating portion 460 may be integrally formed (e.g., a pi-shaped iron member). In some embodiments, the feeding radiation portion 420, the second radiation portion 440, the short-circuit radiation portion 470, and the third radiation portion 480 may also be formed on the non-conductor support element 405 by using laser engraving (LASER DIRECT structures, LDS). The remaining features of the hybrid antenna structure 400 of fig. 4 are similar to those of the hybrid antenna structure 100 of fig. 1, so that similar operation effects can be achieved in both embodiments.
The present invention proposes a novel hybrid antenna structure. Compared with the traditional design, the invention has the advantages of at least small size, wide frequency band, proximity sensing, high communication quality, low manufacturing cost and the like, so that the invention is very suitable for being applied to various mobile communication devices, in particular to Narrow frame (Narrow Border) devices.
It should be noted that the device size, device shape, device parameters, and frequency range are not limitations of the present invention. The antenna designer may adjust these settings according to different needs. The hybrid antenna structure of the present invention is not limited to the states illustrated in fig. 1-4. The present invention may include only any one or more features of any one or more of the embodiments of fig. 1-4. In other words, not all of the illustrated features need be implemented in the hybrid antenna structure of the present invention at the same time.
Ordinal numbers such as "first," "second," "third," and the like in the description and in the claims are used for distinguishing between two different elements having the same name and not necessarily for describing a sequential order.
While the invention has been described with reference to the preferred embodiments, it should be understood that the invention is not limited thereto, but rather, it should be apparent to one skilled in the art that various changes and modifications can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
