In some embodiments, the ground element 110 can be implemented by a ground copper foil, which can also be coupled to a system ground plane (not shown) of the hybrid antenna structure 100.

[0095] The feeding radiation portion 120 has a first end 121 and a second end 122, wherein a feeding point FP may be located at the first end 121 of the feeding radiation portion 120. The feeding point FP may also be coupled to a signal source 190. For example, the signal source 190 may be a radio frequency module, which may be used to excite the hybrid antenna structure 100. In some embodiments, the feeding radiation portion 120 may be substantially in the shape of a straight strip, but is not limited thereto.

[0096] The first radiating portion 130 has a first end 131 and a second end 132, each of which may be an open end. In detail, the first radiating portion 130 includes a first segment 134, a second segment 135, and a third segment 136. For example, the first segment 134, the second segment 135, and the third segment 136 may be arranged substantially on a first straight line LN1, wherein the first segment 134 may be adjacent to the first end 131 of the first radiating portion 130, the third segment 136 may be adjacent to the second end 132 of the first radiating portion 130, and the second segment 135 may be coupled between the first segment 134 and the third segment 136. In addition, a first connection point CP1 may be located between the first segment 134 and the second segment 135, and a second connection point CP2 may be located between the second segment 135 and the third segment 136. In some embodiments, the first radiation portion 130 may be substantially in the shape of a long straight strip, but is not limited thereto. It should be noted that the term "adjacent" or "adjacent" in this specification may refer to a situation where the distance between two corresponding elements is less than a predetermined distance (e.g., 10 mm or shorter), and may also include a situation where two corresponding elements are in direct contact with each other (i.e., the aforementioned distance is shortened to 0).

[0097] The second radiating portion 140 has a first end 141 and a second end 142, wherein the second end 142 of the second radiating portion 140 may be an open end. In detail, the second radiating portion 140 includes a fourth section 144 and a fifth section 145. For example, the fourth section 144 and the fifth section 145 may be arranged substantially on a second straight line LN2, wherein the fourth section 144 may be adjacent to the first end 141 of the second radiating portion 140, and the fifth section 145 may be adjacent to the second end 142 of the second radiating portion 140. It should be noted that the second straight line LN2 may be substantially parallel to the aforementioned first straight line LN1. In addition, a third connection point CP3 may be located between the fourth section 144 and the fifth section 145. The third connection point CP3 of the second radiating portion 140 may also be coupled to the second end 122 of the feed radiating portion 120. In some embodiments, the fifth section 145 is adjacent to the third section 136, so that a first coupling gap GC1 is formed between the third section 136 and the fifth section 145. In some embodiments, the second radiation portion 140 may be substantially in a moderate straight strip shape, but is not limited thereto.

[0098] The first connection radiation portion 150 has a first end 151 and a second end 152, wherein the first end 151 of the first connection radiation portion 150 is coupled to the first connection point CP1 of the first radiation portion 130, and the second end 152 of the first connection radiation portion 150 is coupled to the first end 141 of the second radiation portion 140. In some embodiments, the first connection radiation portion 150 may be substantially in the shape of a short straight bar, but is not limited thereto.

[0099] The second connection radiation portion 160 has a first end 161 and a second end 162, wherein the first end 161 of the second connection radiation portion 160 is coupled to the second connection point CP2 of the first radiation portion 130, and the second end 162 of the second connection radiation portion 160 is coupled to the third connection point CP3 of the second radiation portion 140. In some embodiments, the second connection radiation portion 160 can be substantially in the shape of another shorter straight bar, which can be substantially parallel to the first connection radiation portion 150, but is not limited thereto. Therefore, the first radiation portion 130 can be coupled to the second radiation portion 140 via the first connection radiation portion 150 and the second connection radiation portion 160. It should be noted that the first connection radiation portion 150, the second section 135, the second connection radiation portion 160, and the fourth section 144 can form a closed loop together. For example, the aforementioned closed loop can be substantially in the shape of a hollow rectangle, but is not limited thereto.

[0100] The short-circuit radiation portion 170 has a first end 171 and a second end 172, wherein the first end 171 of the short-circuit radiation portion 170 is coupled to the ground potential VSS, and the second end 172 of the short-circuit radiation portion 170 is coupled to the first end 141 of the second radiation portion 140 and the second end 152 of the first connection radiation portion 150. Therefore, the second radiation portion 140 and the first connection radiation portion 150 can be coupled to the ground potential VSS through the short-circuit radiation portion 170. In some embodiments, the short-circuit radiation portion 170 can be substantially N-shaped, but is not limited thereto. It should be noted that the short-circuit radiation portion 170 can be located on another surface, so that the short-circuit radiation portion 170 does not make direct contact with the third radiation portion 180. For example, the short-circuit radiation portion 170 can be disposed on a rear surface of a carrier element, and the third radiation portion 180 can be disposed on a front surface of the aforementioned carrier element (not shown), but is not limited thereto.

[0101] The third radiating portion 180 has a first end 181 and a second end 182, wherein the first end 181 of the third radiating portion 180 is coupled to the integrated module 200, and the second end 182 of the third radiating portion 180 may be an open end. For example, the second end 132 of the first radiating portion 130, the second end 142 of the second radiating portion 140, and the second end 182 of the third radiating portion 180 may all extend in substantially the same direction. In some embodiments, the third radiating portion 180 is adjacent to the second radiating portion 140, so that a second coupling gap GC2 may be formed between the fourth section 144 and the third radiating portion 180. In some embodiments, the third radiating portion 180 may be substantially L-shaped, and may be at least partially parallel to the second radiating portion 140, but is not limited thereto.

[0102] The internal circuit structure of the integrated module 200 is not particularly limited in the present invention. Generally speaking, the integrated module 200 can have the functions of circuit adjustment and proximity sensing at the same time. For example, the third radiating portion 180 can also be coupled to the grounding element 110 via the integrated module 200, but it is not limited thereto.

[0103] In some embodiments, the hybrid antenna structure 100 may include a first frequency band, a second frequency band, a third frequency band, a fourth frequency band, and a fifth frequency band. For example, the first frequency band may be between 617 MHz and 960 MHz, the second frequency band may be between 1400 MHz and 2000 MHz, the third frequency band may be between 2000 MHz and 2690 MHz, the fourth frequency band may be between 3300 MHz and 5000 MHz, and the fifth frequency band may be between 5000 MHz and 5925 MHz. Therefore, the hybrid antenna structure 100 will at least support broadband operation of the new generation 5G (5th Generation Mobile Networks) communication.

[0104] In some embodiments, the operating principle of the hybrid antenna structure 100 may be as follows. The third radiating portion 180 may be excited by coupling of the feed radiating portion 120 and the second radiating portion 140 to generate the aforementioned first frequency band. The feed radiating portion 120, the first section 134, the second section 135, and the second connected radiating portion 160 may be jointly excited to generate the aforementioned second frequency band. The feed radiating portion 120, the third section 136, and the second connected radiating portion 160 may be jointly excited to generate the aforementioned third frequency band. The feed radiating portion 120, the fourth section 144, and the short-circuit radiating portion 170 may be jointly excited to generate the aforementioned fourth frequency band. The second section 135, the fourth section 144, the first connected radiating portion 150, and the second connected radiating portion 160 (i.e., the aforementioned closed loop) may be jointly excited to generate the aforementioned fifth frequency band. The fifth section 145 can be used to fine-tune the impedance matching of the hybrid antenna structure 100, thereby increasing the operational bandwidth of the hybrid antenna structure 100. In addition, the third radiating portion 180 can also be used as a sensing element of the integrated module 200, so that the hybrid antenna structure 100 can also provide a proximity sensing function.

[0105] In some embodiments, the dimensions of the elements of the hybrid antenna structure 100 may be as follows. The length L1 of the third radiating portion 180 may be substantially equal to 0.25 times the wavelength (λ / 4) of the first frequency band of the hybrid antenna structure 100. The total length L2 of the first segment 134, the second segment 135, the second connecting radiating portion 160, and the feeding radiating portion 120 may be substantially equal to 0.25 times the wavelength (λ / 4) of the second frequency band of the hybrid antenna structure 100. The total length L3 of the third segment 136, the second connecting radiating portion 160, and the feeding radiating portion 120 may be substantially equal to 0.25 times the wavelength (λ / 4) of the third frequency band of the hybrid antenna structure 100. The total length L4 of the short-circuit radiating portion 170, the fourth segment 144, and the feeding radiating portion 120 may be substantially equal to 0.5 times the wavelength (λ / 2) of the fourth frequency band of the hybrid antenna structure 100. The total length L5 of the first connected radiating portion 150, the second section 135, the second connected radiating portion 160, and the fourth section 144 (i.e., the aforementioned closed loop) may be substantially equal to 0.5 times the wavelength (λ / 2) of the fifth frequency band of the hybrid antenna structure 100. The width of the first coupling gap GC1 may be less than or equal to 2 mm. The width of the second coupling gap GC2 may be less than or equal to 2 mm. The above size range is obtained based on multiple experimental results, which helps to optimize the operating bandwidth and impedance matching of the hybrid antenna structure 100, and at the same time can reduce the mutual interference (Interference) between the integrated module 200 and the remaining radiating portions.

[0106] The following embodiments will introduce different configurations and detailed structural features of the hybrid antenna structure 100. It must be understood that these drawings and descriptions are only examples and are not intended to limit the patent scope of the present invention.

[0107] Figure 2 A schematic diagram of an integrated module 200 according to an embodiment of the present invention is shown. Figure 2In the embodiment of the present invention, the integrated module 200 includes a filter circuit 270, a proximity sensor (also known as "P-Sensor") 280, and a tuning circuit 290. The internal structures of the filter circuit 270 and the tuning circuit 290 are not particularly limited in the present invention, and they can be adjusted according to different needs. For example, each of the filter circuit 270 and the tuning circuit 290 can each include one or more inductors, one or more capacitors, and one or more resistors. The third radiating portion 180 can also be coupled to the proximity sensor 280 via the filter circuit 270, wherein the filter circuit 270 can also be coupled to the ground potential VSS via the tuning circuit 290. Generally speaking, the third radiating portion 180 can serve as a related sensing pad of the proximity sensor 280, and the filter circuit 270 can 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 addition of the adjustment circuit 290 helps to improve the operating bandwidth of the hybrid antenna structure 100 .

[0108] In detail, the filter circuit 270 includes a first inductor LA, a second inductor LB, a capacitor C1, and a resistor R1, and the adjustment circuit 290 includes a short-circuited path 291, a capacitive path 292, an open-circuited path 293, an inductive path 294, and a switch element 295.

[0109] 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 can also be coupled to the first end 181 of the third radiation 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.

[0110] In the filter circuit 270, the capacitor C1 can be used as a high-pass filter element to prevent the low-frequency noise of the adjacent sensor 280 from entering the adjustment circuit 290. According to actual measurement results, the addition of the first inductor LA can reduce the probability of malfunction of the adjacent sensor 280 when the adjustment circuit 290 is switched. The second inductor LB can be used as a low-pass filter element, which can prevent the adjacent sensor 280 from negatively affecting the radiation performance of the hybrid antenna structure 100. In addition, the resistor R1 can be used to reduce the mutual interference between the adjacent sensor 280 and the remaining radiating parts.

[0111] The short-circuit path 291, the capacitor path 292, the disconnect path 293, and the inductor path 294 can 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 between the short-circuit path 291, the capacitor path 292, the disconnect path 293, and the inductor path 294 according to a control signal SC. Therefore, the second node N2 can be coupled to the ground potential VSS via the path selected by the switch 295. For example, the control signal SC can be generated by a processor according to a user input (not shown), but is not limited thereto.

[0112] When the switch 295 switches between 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. According to actual measurement results, this design helps to significantly increase the operating bandwidth of the hybrid antenna structure 100, especially the aforementioned first frequency band and the second frequency band.

Compared with the conventional design, the present invention has at least the advantages of small size, wide bandwidth, proximity sensing, high communication quality, and low manufacturing cost, so it is very suitable for application in various mobile communication devices, especially narrow border devices.

[0118] It is worth noting that the above-mentioned element size, element shape, element parameters, and frequency range are not limiting conditions of the present invention. Antenna designers can adjust these settings according to different needs. The hybrid antenna structure of the present invention is not limited to Figure 1-Figure 4 The present invention may only include Figure 1-Figure 4 In other words, not all the features shown in the figures need to be implemented in the hybrid antenna structure of the present invention at the same time.
