Description

Technical Field

[0001] The present invention relates to communication technologies, and more particularly to antenna modules. Background Art

[0002] Nowadays, the volumes of various electronic devices are gradually shrinking. Therefore, the volume of the antenna inside the electronic device also needs to be reduced. Generally, the antenna height is reduced to reduce the volume of the antenna. This type of antenna is also called a low profile antenna. However, there is a positive correlation between the antenna height and the antenna characteristics. Specifically, when the antenna height is reduced, the radiation element of the antenna will be closer to the grounding element, resulting in a capacitive effect, causing the impedance of the antenna to be capacitive. As such, the bandwidth of the antenna will be reduced and the antenna characteristics will be poor. Summary of the Invention

[0003] In view of the above, the present invention provides an antenna module. The antenna module includes a first inverted-F antenna resonant element and an inductive circuit. The first inverted-F antenna resonant element includes a first radiation section. The first radiation section includes a first main section, a first feeding section having a first feeding point, and a first short-circuit section having a first short-circuit point. The inductive circuit includes a first inductive unit providing a first inductive path and a second inductive unit providing a second inductive path. The first inductive path and the second inductive path are adjacent and non-connected. The first inductive path includes two ends. One of the two ends of the first inductive path is connected to a feeding source. The first feeding point is connected to any one of the two ends of the first inductive path. The second inductive path includes two ends. One of the two ends of the second inductive path is connected to a grounding portion. The first short-circuit point is connected to any one of the two ends of the second inductive path.

[0004] In summary, according to some embodiments, through the inductive circuit, the present invention can reduce the capacitive effect between the first radiation section of the first inverted-F antenna resonant element and the grounding portion while the antenna height is reduced (i.e., low profile), so as to improve the bandwidth and antenna characteristics of the antenna module. In some embodiments, in addition to reducing the capacitive effect between the first radiation section of the first inverted-F antenna resonant element and the grounding portion, the inductive circuit of the present invention also reduces the capacitive effect between the second radiation section of the second inverted-F antenna resonant element and the grounding portion, so as to further improve the bandwidth and antenna characteristics of the antenna module. In some embodiments, through the radiation characteristics of the first inverted-F antenna resonant element, the second inverted-F antenna resonant element, and other radiation elements (such as parasitic elements, monopole antenna elements, etc.), the antenna module can still have good bandwidth and antenna characteristics when in an environment adjacent to a metal obstacle (for example, the distance between the antenna module and the metal obstacle is less than 5 mm (millimeters)).

[0127] Refer to Figure 1 , which is a schematic structural diagram of an antenna module 10 according to some embodiments of the present invention. The antenna module 10 includes a first inverted-F antenna resonant element 20 and an inductive circuit 30. The first inverted-F antenna resonant element 20 includes a first radiation section 21. The first radiation section 21 is used to transmit (excite) and receive wireless signals (electromagnetic waves). The inductive circuit 30 includes a first inductive unit 31 and a second inductive unit 32. The first inductive unit 31 provides a first inductive path, and the second inductive unit 32 provides a second inductive path. The first inductive path and the second inductive path are adjacent and non-connected to generate mutual inductance. By the self-inductance of the first inductive path and the second inductive path and the mutual inductance therebetween, the capacitive effect between the first radiation section 21 and the grounding portion 40 is reduced. The grounding portion 40 is connected to the reference ground terminal (not shown in the figure) of the main board to obtain a reference ground. By reducing the aforementioned capacitive effect, the bandwidth and antenna characteristics of the antenna module 10 can be improved.

[0128] Such as Figure 1As shown, the first radiation section 21 includes a first main section 22, a first feeding section 23 having a first feeding point F1, and a first short - circuit section 24 having a first short - circuit point S1. The first inductive path includes two ends (i.e., a first end E1 and a second end E2). One of the two ends of the first inductive path is connected to a feeding source FD. For example, the second end E2 of the first inductive path is connected to the feeding source FD. The first feeding point F1 is connected to either of the two ends of the first inductive path. For example, the first feeding point F1 is connected to the first end E1 of the first inductive path (as shown by the dashed line DL1) or the second end E2 (as shown by the dashed line DL2). The second inductive path includes two ends (i.e., a third end E3 and a fourth end E4). One of the two ends of the second inductive path is connected to a ground portion 40. For example, the fourth end E4 of the second inductive path is connected to the ground portion 40. The first short - circuit point S1 is connected to either of the two ends of the second inductive path. For example, the first short - circuit point S1 is connected to the third end E3 of the second inductive path (as shown by the dashed line DL3) or the fourth end E4 (as shown by the dashed line DL4). In this way, the energy of the feeding source FD flows through the resonance path provided by the first radiation section 21, passes through the inductive circuit 30 and the ground portion 40 to form a resonance loop, so that the antenna module 10 can excite at least one resonance band, such as a low - frequency band, a medium - frequency band, and a high - frequency band. The low - frequency band can be between 2300 megahertz (MHz) and 2600 MHz, the medium - frequency band can be between 5000 MHz and 6500 MHz, and the high - frequency band can be between 6500 MHz and 8000 MHz to meet the bandwidth operation of communication protocols (such as Wi - Fi 7). The above - mentioned architecture will be described below with multiple embodiments.

[0129] Referring to Figure 2 , is a three - dimensional schematic diagram of the first embodiment of the antenna module 10 of the present invention. In the first embodiment of the antenna module 10, the antenna module 10 includes a first inverted - F antenna resonant element 20, an inductive circuit 30, and a substrate 100. The first feeding section 23 and the first short - circuit section 24 of the first inverted - F antenna resonant element 20 are connected to the first main section 22. The first feeding point F1 and the feeding source FD are respectively connected to the two ends of the first inductive path (i.e., are respectively connected to different ends of the first inductive path). For example, the first feeding point F1 is connected to the first end E1 of the first inductive path of the inductive circuit 30, and the feeding source FD is connected to the second end E2 of the first inductive path of the inductive circuit 30. The first short - circuit point S1 and the ground portion 40 are respectively connected to the two ends of the second inductive path (i.e., are respectively connected to different ends of the second inductive path). For example, the first short - circuit point S1 is connected to the third end E3 of the second inductive path of the inductive circuit 30, and the ground portion 40 is connected to the fourth end E4 of the second inductive path of the inductive circuit 30.

[0130] As Figure 2As shown, the fourth end E4 of the second inductive path of the inductance circuit 30 is connected to the ground wire segment 41 of the ground portion 40. The first short - circuit section 24 has two sections (i.e., the first section 241 and the second section 242). The first section 241 of the first short - circuit section 24 has a first short - circuit point S1 and is connected to the third end E3 of the second inductive path of the inductance circuit 30. The first section 241 of the first short - circuit section 24 extends from the inductance circuit 30 along a direction parallel to the edge of the ground portion 40 (specifically, along the linear ground wire segment 41 of the ground portion 40, such as along the horizontal direction) for a certain length. The second section 242 of the first short - circuit section 24 continues from the end of the first section 241 of the first short - circuit section 24 and extends in a direction away from the ground portion 40 (such as along the vertical direction) for a certain length, and the end of the second section 242 of the first short - circuit section 24 is connected to the first main section 22. The first main section 22 extends from the end of the second section 242 of the first short - circuit section 24 along a direction parallel to the first section 241 of the first short - circuit section 24 for a certain length.

[0131] The second end E2 of the first inductive path of the inductance circuit 30 is connected to the feed source FD via a feed wire segment 50. The first feed section 23 has a first feed point F1 and is connected to the first end E1 of the first inductive path of the inductance circuit 30. The first feed section 23 extends from the inductance circuit 30 along a direction parallel to the second section 242 of the first short - circuit section 24, and the end of the first feed section 23 is connected to the area between the two ends of the first main section 22. That is to say, the first main section 22 has two sections (i.e., the first section 221 and the second section 222). The first section 221 of the first main section 22 extends from the end of the second section 242 of the first short - circuit section 24 along a direction parallel to the first section 241 of the first short - circuit section 24 to the end of the first feed section 23. The second section 222 of the first main section 22 continues from the end of the first section 221 of the first main section 22 and extends along a direction parallel to the first section 241 of the first short - circuit section 24 for a certain length. In this way, the first feed section 23 and the second section 222 of the first main section 22 jointly excite the first resonance frequency band (such as the low - frequency band), the first feed section 23, the first section 221 of the first main section 22, and the first short - circuit section 24 jointly excite the second resonance frequency band (such as the medium - frequency band), and the ground wire segment 41 excites the third resonance frequency band (such as the high - frequency band).

[0132] As described above, since the feeding source FD and the first feeding point F1 are different ends of the first inductive path, the feeding source FD is connected to the first feeding point F1 via the first inductive path of the inductance circuit 30 and the feeding wire segment 50. Since the grounding portion 40 and the first short - circuit point S1 are different ends of the second inductive path, the first short - circuit point S1 is connected to the grounding wire segment 41 of the grounding portion 40 via the second inductive path of the inductance circuit 30.

[0133] As Figure 2 shown, in the first embodiment of the antenna module 10, there is a distance between the first feeding section 23 and the first short - circuit section 24 in the horizontal direction. Specifically, there is a distance between the first feeding section 23 and the second section 242 of the first short - circuit section 24 in the horizontal direction. By adjusting the size of this distance, the impedance matching of the entire antenna module 10 is adjusted.

[0134] As Figure 2 shown, in some exemplary embodiments of the first embodiment of the antenna module 10, the extension length of the first section 241 of the first short - circuit section 24 is the same as the extension length of the first section 221 of the first main section 22, the extension length of the second section 242 of the first short - circuit section 24 is the same as the extension length of the first feeding section 23, and the extension length of the second section 222 of the first main section 22 is greater than the extension length of the first section 221 of the first main section 22. In this way, the first inverted - F antenna resonant element 20 can have good antenna characteristics.

[0135] Referring to Figure 3 and Figure 4 . Figure 3 is a perspective schematic diagram of the second embodiment of the antenna module 10 of the present invention. Figure 4 is a perspective schematic diagram of the third embodiment of the antenna module 10 of the present invention. The difference from the first embodiment of the antenna module 10 is that in the second and third embodiments of the antenna module 10, the antenna module 10 further includes a first parasitic element 60, which is connected to the grounding portion 40. The first parasitic element 60 and the first inverted - F antenna resonant element 20 are separated from each other and are spaced apart from the first main section 22 by a first coupling gap CG1. Through the first coupling gap CG1, the energy of the feeding source FD can be coupled from the first inverted - F antenna resonant element 20 to the first parasitic element 60 and pass through the grounding portion 40 to form a resonance circuit, so that the first parasitic element 60 assists the first inverted - F antenna resonant element 20 to excite the first resonance band.

[0136] As Figure 3 and Figure 4 shown, the first parasitic element 60 has two sections (i.e., the first section 601 and the second section 602). The first section 601 of the first parasitic element 60 extends from the grounding portion 40 (as Figure 3(as shown) or as Figure 4 shown, a ground wire segment 41 of the grounding portion 40 extends a length along a second segment 242 parallel to the first short - circuit segment 24. A second segment 602 of the first parasitic element 60 is connected to the end of a first segment 601 of the first parasitic element 60 to extend a length along a direction parallel to the first main segment 22. The second segment 602 of the first parasitic element 60 is spaced from the first main segment 22 by a first coupling gap CG1.

[0137] As Figure 3 shown, in a second embodiment of the antenna module 10, the first parasitic element 60 is spaced from the first short - circuit segment 24 by a second coupling gap CG2. For example, the first segment 601 of the first parasitic element 60 is spaced from the second segment 242 of the first short - circuit segment 24 by the second coupling gap CG2. Through the second coupling gap CG2, the energy fed from the feed source FD can be coupled from the first inverted - F antenna resonant element 20 to the first parasitic element 60 and pass through the grounding portion 40 to form a resonance circuit, so that the first parasitic element 60 assists the first inverted - F antenna resonant element 20 to excite a second resonance band.

[0138] As Figure 3 shown, in a second embodiment of the antenna module 10, the first parasitic element 60 is located outside the first main segment 22 (from the perspective of the grounding portion 40), that is, the first main segment 22 is located between the first parasitic element 60 and the grounding portion 40. As Figure 4 shown, in a third embodiment of the antenna module 10, the first parasitic element 60 is located inside the first main segment 22 (from the perspective of the grounding portion 40), that is, the first parasitic element 60 is located between the first main segment 22 and the grounding portion 40.

[0139] As Figure 3 and Figure 4 shown, in some exemplary cases of the second and third embodiments of the antenna module 10, the end of the second segment 602 of the first parasitic element 60 and the end of the second segment 222 of the first main segment 22 extend to the same axis.

[0140] As Figures 2 to 4 shown, the first short - circuit point S1 of the first inverted - F antenna resonant element 20 and the grounding portion 40 are respectively connected to two ends of a second inductive path. Therefore, after the energy fed from the feed source FD flows through the first inductive path to the first inverted - F antenna resonant element 20, it flows to the grounding portion 40 through the second inductive path. In this way, the energy fed from the feed source FD can flow in the first and second inductive paths, thereby reducing the capacitive effect between the radiating element (such as the first inverted - F antenna resonant element 20) and the grounding portion 40 through the self - inductance of each of the two inductive paths and the mutual inductance between them.

[0141] Refer to Figures 5 to 7 .Figure 5 It is a perspective schematic diagram of the fourth embodiment of the antenna module 10 of the present invention. Figure 6 It is a perspective schematic diagram of the fifth embodiment of the antenna module 10 of the present invention. Figure 7 It is a perspective schematic diagram of the sixth embodiment of the antenna module 10 of the present invention. In the fourth to sixth embodiments of the antenna module 10, the antenna module 10 includes a first inverted-F antenna resonant element 20, an inductance circuit 30, a second parasitic element 80, and a substrate 100. The first feeding section 23 and the first short-circuit section 24 of the first inverted-F antenna resonant element 20 are connected to the first main section 22. The first feeding point F1 and the feeding source FD are respectively connected to two ends of the first inductive path (i.e., are respectively connected to different ends of the first inductive path). For example, the first feeding point F1 is connected to the first end E1 of the first inductive path of the inductance circuit 30, and the feeding source FD is connected to the second end E2 of the first inductive path of the inductance circuit 30. The first short-circuit point S1 and the grounding portion 40 are both connected to the same one of the two ends of the second inductive path (i.e., are both connected to the same end of the second inductive path). For example, the first short-circuit point S1 and the grounding portion 40 are both connected to the third end E3 of the second inductive path of the inductance circuit 30, or the first short-circuit point S1 and the grounding portion 40 are both connected to the fourth end E4 of the second inductive path of the inductance circuit 30.

[0142] The second end E2 of the first inductive path of the inductance circuit 30 is connected to the feeding source FD via a feeding conductive segment 50. The first feeding section 23 has a first feeding point F1 and is connected to the first end E1 of the first inductive path of the inductance circuit 30. The first feeding section 23 extends a length in a direction away from the grounding portion 40 (such as along the vertical direction) from the inductance circuit 30, and the end of the first feeding section 23 is connected to the first main section 22. The first main section 22 extends a length along an edge parallel to the grounding portion 40 (such as along the horizontal direction) from the end of the first feeding section 23. The first short-circuit section 24 has a first short-circuit point S1 and is connected to the grounding portion 40, thereby connecting to one of the two ends of the second inductive path of the inductance circuit 30. That is to say, the first short-circuit point S1 is directly connected to the grounding portion 40 so that the first short-circuit point S1 and the grounding portion 40 are both connected to the same end of the second inductive path. The first short-circuit section 24 extends from the grounding portion 40 towards the region between the two ends of the first main section 22, and the end of the first short-circuit section 24 is connected to the region between the two ends of the first main section 22. Thus, the first main section 22, the first feeding section 23, and the first short-circuit section 24 jointly excite a first resonance band.

[0143] The second parasitic element 80 and the grounding portion 40 are respectively connected to two ends of the second inductive path (i.e., different ends of the second inductive path). For example, the second parasitic element 80 is connected to the third end E3 of the second inductive path of the inductive circuit 30, and the grounding portion 40 is connected to the fourth end E4 of the second inductive path of the inductive circuit 30; or the second parasitic element 80 is connected to the fourth end E4 of the second inductive path of the inductive circuit 30, and the grounding portion 40 is connected to the third end E3 of the second inductive path of the inductive circuit 30. The second parasitic element 80 and the first inverted-F antenna resonant element 20 are separated from each other and are spaced apart by a fourth coupling gap CG4 from the first main section 22. Through the fourth coupling gap CG4, the energy fed into the source FD can be coupled from the first inverted-F antenna resonant element 20 to the second parasitic element 80 and pass through the grounding portion 40 to form a resonance circuit, so that the second parasitic element 80 excites a second resonance band, and the first inverted-F antenna resonant element 20 and the second parasitic element 80 jointly excite a third resonance band.

[0144] As Figure 5 shown, in the fourth embodiment of the antenna module 10, the first short-circuit section 24 has two sections (i.e., the first section 241 and the second section 242), the grounding portion 40 has a grounding wire section 41, and the second parasitic element 80 has three sections (i.e., the first section 801, the second section 802, and the third section 803). The fourth end E4 of the second inductive path of the inductive circuit 30 is connected to the grounding wire section 41 of the grounding portion 40. The second section 242 of the first short-circuit section 24 is in an inverted triangle shape, and the base of the inverted triangle is connected to the area between the two ends of the first main section 22. The first section 241 of the first short-circuit section 24 is in a straight line shape and has a first short-circuit point S1 to connect to the grounding wire section 41 of the grounding portion 40. Thus, both the first short-circuit point S1 and the grounding portion 40 are connected to the fourth end E4 of the second inductive path. The first section 241 of the first short-circuit section 24 extends from the grounding wire section 41 of the grounding portion 40 toward the area between the two ends of the first main section 22 (e.g., obliquely extends), and the apex angle of the second section 242 presented in the inverted triangle shape is continuous with the end of the first section 241 of the first short-circuit section 24. The width of the end of the first main section 22 is smaller than other areas of the first main section 22.

[0145] The first section 801 of the second parasitic element 80 is connected to the third end E3 of the second inductive path of the inductive circuit 30. The first section 801 of the second parasitic element 80 extends a length from the inductive circuit 30 along a direction parallel to the first main section 22 of the first inverted-F antenna resonant element 20. The second section 802 of the second parasitic element 80 is connected to the end of the first section 801 of the second parasitic element 80 and extends a length along a direction parallel to the first feeding section 23 of the first inverted-F antenna resonant element 20. The third section 803 of the second parasitic element 80 is connected to the end of the second section 802 of the second parasitic element 80 and extends a length along a direction parallel to the first main section 22, and the second section 802 of the second parasitic element 80 is spaced from the first main section 22 by a fourth coupling gap CG4.

[0146] As Figure 6 shown, the difference from the fourth embodiment of the antenna module 10 is that in the fifth embodiment of the antenna module 10, the first shorting section 24 does not have the first section 241, and the grounding portion 40 further has a triangular conductive region 42. The bottom side of the triangular conductive region 42 is connected to the grounding wire segment 41. The first shorting point S1 is located at the apex angle of the second section 242 presented in an inverted triangle and is connected to the apex angle of the triangular conductive region 42, and thus is connected to the fourth end E4 of the second inductive path via the grounding wire segment 41. The width of the end of the first main section 22 is greater than other regions of the first main section 22. The extending length of the third section 803 of the second parasitic element 80 in the fifth embodiment of the antenna module 10 is less than the extending length of the third section 803 of the second parasitic element 80 in the fourth embodiment of the antenna module 10. In this way, the antenna module 10 can meet the impedance matching required in different scenarios.

[0147] As Figure 7As shown, the difference from the fourth embodiment of the antenna module 10 is that in the sixth embodiment of the antenna module 10, the grounding portion 40 does not have a grounding wire segment 41 connected to the fourth end E4 of the second inductive path of the inductive circuit 30, but is connected to the third end E3 of the second inductive path of the inductive circuit 30. The second parasitic element 80 is connected to the fourth end E4 of the second inductive path of the inductive circuit 30. Herein, the second parasitic element 80 is in a straight line shape, but the embodiments of the present invention are not limited to this shape. The first short-circuit point S1 of the first segment 241 of the first short-circuit segment 24 is connected to other regions of the grounding portion 40. Thus, both the first short-circuit point S1 and the grounding portion 40 are connected to the third end E3 of the second inductive path. The first segment 241 of the first short-circuit segment 24 extends from other regions of the grounding portion 40 toward the region between the two ends of the first main segment 22 (e.g., obliquely extends). The second parasitic element 80 extends a length along a direction parallel to the first main segment 22 of the first inverted-F antenna resonant element 20 from the inductive circuit 30, and the second parasitic element 80 is spaced apart from the first main segment 22 by a fourth coupling gap CG4. In this embodiment, the second parasitic element 80 is located inside the first main segment 22 (from the perspective of the grounding portion 40), that is, the second parasitic element 80 is located between the first main segment 22 and the grounding portion 40. Thus, the antenna module 10 can satisfy the impedance matching required in different scenarios.

[0148] As Figures 5 to 7 shown, although the first short-circuit point S1 of the first inverted-F antenna resonant element 20 is connected to the grounding portion 40 to jointly connect to the same end of the second inductive path as the grounding portion 40, rather than the grounding portion 40 and the second inductive path being respectively connected to different ends. However, since the second parasitic element 80 is connected to the second inductive path of the inductive circuit 30, after the energy of the feeding source FD flows through the first inductive path to the first inverted-F antenna resonant element 20, a part of the energy flows to the grounding portion 40, and another part of the energy is coupled to the second parasitic element 80 and then flows to the grounding portion 40 via the second inductive path. Thus, the energy of the feeding source FD can flow in the first and second inductive paths, thereby reducing the capacitive effect between the radiating element (such as the first inverted-F antenna resonant element 20) and the grounding portion 40 through the self-inductance of each of the two inductive paths and the mutual inductance between them.

[0149] Referring to Figure 8, is a perspective schematic diagram of the seventh embodiment of the antenna module 10 of the present invention. In the seventh embodiment of the antenna module 10, the antenna module 10 includes a first inverted-F antenna resonant element 20, an inductance circuit 30, a second inverted-F antenna resonant element 70, and a substrate 100. The first feeding section 23 of the first inverted-F antenna resonant element 20 is connected to the first main section 22, and the first short-circuit section 24 is connected to the first feeding section 23. The first feeding point F1 and the feeding source FD are respectively connected to two ends of the first inductive path (i.e., are respectively connected to different ends of the first inductive path). For example, the first feeding point F1 is connected to the first end E1 of the first inductive path of the inductance circuit 30, and the feeding source FD is connected to the second end E2 of the first inductive path of the inductance circuit 30. The first short-circuit point S1 and the grounding portion 40 are both connected to the same one of the two ends of the second inductive path (i.e., are both connected to the same end of the second inductive path). For example, the first short-circuit point S1 and the grounding portion 40 are both connected to the fourth end E4 of the second inductive path of the inductance circuit 30.

[0150] The second end E2 of the first inductive path of the inductance circuit 30 is connected to the feeding source FD via the feeding wire segment 50. The first feeding section 23 has the first feeding point F1 and is connected to the first end E1 of the first inductive path of the inductance circuit 30. The first feeding section 23 extends a length in a direction away from the grounding portion 40 (such as along the vertical direction) from the inductance circuit 30, and the end of the first feeding section 23 is connected to the first main section 22. The first main section 22 extends a length from the end of the first feeding section 23 along an edge parallel to the grounding portion 40 (specifically, along the linear grounding wire segment 41 parallel to the grounding portion 40, such as along the horizontal direction). The fourth end E4 of the second inductive path of the inductance circuit 30 is connected to the grounding wire segment 41 of the grounding portion 40. The first short-circuit section 24 has two sections (i.e., the first section 241 and the second section 242). The first section 241 of the first short-circuit section 24 has the first short-circuit point S1 and is connected to the grounding wire segment 41 of the grounding portion 40. Thus, the first short-circuit point S1 and the grounding portion 40 are both connected to the fourth end E4 of the second inductive path of the inductance circuit 30. The first section 241 of the first short-circuit section 24 extends a length along a direction parallel to the first feeding section 23 from the grounding wire segment 41 of the grounding portion 40, the second section 242 of the first short-circuit section 24 continues from the end of the first section 241 of the first short-circuit section 24 to extend a length along a direction parallel to the first main section 22, and the end of the second section 242 of the first short-circuit section 24 is connected to an area between the two ends of the first feeding section 23. Thus, the first main section 22, the first feeding section 23, and the first short-circuit section 24 jointly excite the first resonance band.

[0151] The second inverted-F antenna resonant element 70 includes a second radiation section 71. The second radiation section 71 is used to transmit (excite) and receive wireless signals (electromagnetic waves). The second radiation section 71 includes a second main section 72, a second feeding section 73 having a second feeding point F2, and a second short-circuit section 74 having a second short-circuit point S2. The second feeding point F2 and the feeding source FD are both connected to the same one of the two ends of the first inductive path (i.e., both are connected to the same end of the first inductive path). For example, the second feeding point F2 and the feeding source FD are both connected to the second end E2 of the first inductive path of the inductive circuit 30. Specifically, the second feeding point F2 is connected to the second end E2 and the feeding source FD via a feeding wire segment 50. Thus, both the second feeding point F2 and the feeding source FD are connected to the second end E2 via the feeding wire segment 50. The second short-circuit point S2 and the grounding portion 40 are respectively connected to the two ends of the second inductive path (i.e., are respectively connected to different ends of the second inductive path). For example, the second short-circuit point S2 is connected to the third end E3 of the second inductive path of the inductive circuit 30, and the grounding portion 40 is connected to the fourth end E4 of the second inductive path of the inductive circuit 30. The second feeding section 73 is connected to the second main section 72, and the second short-circuit section 74 is connected to the second feeding section 73.

[0152] Specifically, the feeding wire segment 50 extends a length from the inductive circuit 30 along an edge parallel to the grounding portion 40 (specifically, along a linear grounding wire segment 41 parallel to the grounding portion 40, such as along the horizontal direction), and the end of the feeding wire segment 50 is connected to the feeding source FD. The second feeding section 73 has a second feeding point F2 and is connected to the end of the feeding wire segment 50. The second feeding section 73 extends a length from the end of the feeding wire segment 50 in a direction away from the grounding portion 40 (such as along the vertical direction), and the end of the second feeding section 73 is connected to the second main section 72. The second main section 72 extends a length from the end of the second feeding section 73 along a direction parallel to the feeding wire segment 50.

[0153] The second short - circuit section 74 has three sections (i.e., the first section 741, the second section 742, and the third section 743). The first section 741 of the second short - circuit section 74 has a second short - circuit point S2 and is connected to the third end E3 of the second inductive path of the inductive circuit 30. The first section 741 of the second short - circuit section 74 extends a length along a direction parallel to the feeding wire segment 50 from the inductive circuit 30. The second section 742 of the second short - circuit section 74 is connected to the end of the first section 741 of the second short - circuit section 74 and extends a length along a direction parallel to the second feeding section 73. The third section 743 of the second short - circuit section 74 is connected to the end of the second section 742 of the second short - circuit section 74 and extends a length along a direction parallel to the feeding wire segment 50, and the end of the third section 743 of the second short - circuit section 74 is connected to the region between the two ends of the second feeding section 73. In this way, the energy of the feeding source FD flows through the resonance path provided by the second radiation section 71, and passes through the inductive circuit 30 and the grounding portion 40 to form a resonance loop, so that the antenna module 10 can excite a resonance frequency band, such as the second resonance frequency band. Furthermore, by means of the self - inductance of the first inductive path and the second inductive path and the mutual inductance between them, the capacitive effect between the second radiation section 71 and the grounding portion 40 can be reduced, thereby further improving the bandwidth and antenna characteristics of the antenna module 10.

[0154] As Figure 8 shown, in the seventh embodiment of the antenna module 10, the second inverted - F antenna resonant element 70 and the first inverted - F antenna resonant element 20 are separated from each other, and the second main section 72 and the first main section 22 are spaced apart by a third coupling gap CG3. Through the third coupling gap CG3, the energy of the first inverted - F antenna resonant element 20 and the second inverted - F antenna resonant element 70 can be mutually coupled, so that the first inverted - F antenna resonant element 20 and the second inverted - F antenna resonant element 70 jointly excite the third resonance frequency band.

[0155] As Figure 8 shown, the first short - circuit point S1 of the first inverted - F antenna resonant element 20 is connected to the grounding portion 40 to be commonly connected to the same end of the second inductive path as the grounding portion 40. The second short - circuit point S2 of the second inverted - F antenna resonant element 70 and the grounding portion 40 are respectively connected to the two ends of the second inductive path. Therefore, after a part of the energy of the feeding source FD flows through the first inductive path to the first inverted - F antenna resonant element 20, it flows to the grounding portion 40, and another part of the energy directly flows to the second inverted - F antenna resonant element 70. After passing through the second inductive path, it flows to the grounding portion 40. In this way, the energy of the feeding source FD can flow in the first and second inductive paths, so as to reduce the capacitive effect between the radiation elements (the first inverted - F antenna resonant element 20 and the second inverted - F antenna resonant element 70) and the grounding portion 40 through the self - inductance of the two inductive paths and the mutual inductance between them.

[0156] Referring toFigure 9 , which is a perspective schematic diagram of the eighth embodiment of the antenna module 10 of the present invention. In the eighth embodiment of the antenna module 10, the antenna module 10 includes a first inverted-F antenna resonant element 20, an inductive circuit 30, a second parasitic element 80, and a substrate 100. Among them, the first inverted-F antenna resonant element 20 of the eighth embodiment of the antenna module 10 is similar to the first inverted-F antenna resonant element 20 of the seventh embodiment of the antenna module 10, and the second parasitic element 80 of the eighth embodiment of the antenna module 10 is similar to the second parasitic element 80 of the fourth and fifth embodiments of the antenna module 10, so they will not be repeated here.

[0157] As Figure 9 shown, although the first short circuit point S1 of the first inverted-F antenna resonant element 20 is connected to the grounding portion 40 to jointly connect to the same end of the second inductive path as the grounding portion 40, rather than being separately connected to different ends of the second inductive path by the grounding portion 40. However, since the second parasitic element 80 is connected to the second inductive path of the inductive circuit 30, after the energy fed by the feeding source FD flows through the first inductive path to the first inverted-F antenna resonant element 20, a part of the energy flows to the grounding portion 40, and another part of the energy is coupled to the second parasitic element 80 and then flows to the grounding portion 40 through the second inductive path. In this way, the energy fed by the feeding source FD can flow in the first and second inductive paths, thereby reducing the capacitive effect between the radiating element (the first inverted-F antenna resonant element 20) and the grounding portion 40 through the self-inductance of each of the two inductive paths and the mutual inductance between them.

[0158] Referring to Figure 10 , which is a perspective schematic diagram of the ninth embodiment of the antenna module 10 of the present invention. In the ninth embodiment of the antenna module 10, the antenna module 10 includes a first inverted-F antenna resonant element 20, an inductive circuit 30, a monopole antenna element 90, and a substrate 100. The first feeding section 23 of the first inverted-F antenna resonant element 20 is connected to the first main section 22, and the first short circuit section 24 is connected to the first feeding section 23. The first feeding point F1 and the feeding source FD are both connected to the same one of the two ends of the first inductive path (that is, both are connected to the same end of the first inductive path). For example, the first feeding point F1 and the feeding source FD are both connected to the second end E2 of the first inductive path of the inductive circuit 30. The first short circuit point S1 and the grounding portion 40 are respectively connected to the two ends of the second inductive path (that is, are respectively connected to different ends of the second inductive path). For example, the first short circuit point S1 is connected to the third end E3 of the second inductive path of the inductive circuit 30, and the grounding portion 40 is connected to the fourth end E4 of the second inductive path of the inductive circuit 30.

[0159] The second end E2 of the first inductive path of the inductive circuit 30 is connected to the feeding source FD via the feeding wire segment 50. The feeding wire segment 50 extends a length from the inductive circuit 30 along a direction parallel to the edge of the grounding portion 40 (specifically, along the linear grounding wire segment 41 of the grounding portion 40, such as along the horizontal direction), and the end of the feeding wire segment 50 is connected to the feeding source FD. The first feeding section 23 has a first feeding point F1 and is connected to the end of the feeding wire segment 50. That is to say, the first feeding point F1 is connected to the second end E2 of the first inductive path of the inductive circuit 30 and the feeding source FD via the feeding wire segment 50. Thus, both the first feeding point F1 and the feeding source FD are connected to the second end E2 of the first inductive path of the inductive circuit 30 via the feeding wire segment 50. The first feeding section 23 extends a length from the end of the feeding wire segment 50 in a direction away from the grounding portion 40 (such as along the vertical direction), and the end of the first feeding section 23 is connected to the first main section 22. The first main section 22 extends a length from the end of the first feeding section 23 along a direction parallel to the feeding wire segment 50.

[0160] The fourth end E4 of the second inductive path of the inductive circuit 30 is connected to the grounding wire segment 41 of the grounding portion 40. The first short - circuit section 24 has three sections (i.e., the first section 241, the second section 242, and the third section 243). The first section 241 of the first short - circuit section 24 has a first short - circuit point S1 and is connected to the third end E3 of the second inductive path of the inductive circuit 30. The first section 241 of the first short - circuit section 24 extends a length from the inductive circuit 30 along a direction parallel to the feeding wire segment 50. The second section 242 of the first short - circuit section 24 continues from the end of the first section 241 of the first short - circuit section 24 and extends a length along a direction parallel to the first feeding section 23. The third section 243 of the first short - circuit section 24 continues from the end of the second section 242 of the first short - circuit section 24 and extends a length along a direction parallel to the feeding wire segment 50, and the end of the third section 243 of the first short - circuit section 24 is connected to the region between the two ends of the first feeding section 23. Thus, the first main section 22, the first feeding section 23, and the first short - circuit section 24 jointly excite the second resonance band.

[0161] The monopole antenna element 90 and the feeding source FD are respectively connected to two ends of the first inductive path (i.e., different ends of the first inductive path). For example, the monopole antenna element 90 is connected to the first end E1 of the first inductive path of the inductance circuit 30, and the feeding source FD is connected to the second end E2 of the first inductive path of the inductance circuit 30. The monopole antenna element 90 and the first inverted-F antenna resonant element 20 are separated from each other and are spaced apart from the first main section 22 by a fifth coupling gap CG5. Specifically, the monopole antenna element 90 has two sections (i.e., the first section 901 and the second section 902). The first section 901 of the monopole antenna element 90 is connected to the first end E1 of the first inductive path of the inductance circuit 30. The first section 901 of the monopole antenna element 90 extends a length along a direction parallel to the first feeding section 23 from the inductance circuit 30. The second section 902 of the monopole antenna element 90 continues from the end of the first section 901 of the monopole antenna element 90 and extends a length along a direction parallel to the feeding wire section 50, and the second section 902 of the monopole antenna element 90 is spaced apart from the first main section 22 by the fifth coupling gap CG5. Thus, the energy of the feeding source FD flows through the resonance path provided by the monopole antenna element 90 to excite the first resonance band. Furthermore, through the fifth coupling gap CG5, the energy of the first inverted-F antenna resonant element 20 and the monopole antenna element 90 can be mutually coupled, so that the first inverted-F antenna resonant element 20 and the monopole antenna element 90 jointly excite the third resonance band.

[0162] As Figure 10 shown, the first short-circuit point S1 of the first inverted-F antenna resonant element 20 and the grounding portion 40 are respectively connected to two ends of the second inductive path. Therefore, a part of the energy of the feeding source FD flows to the monopole antenna element 90 after passing through the first inductive path, is coupled to the first inverted-F antenna resonant element 20, and then flows to the grounding portion 40 after passing through the second inductive path. Another part of the energy directly flows to the first inverted-F antenna resonant element 20 and then flows to the grounding portion 40 after passing through the second inductive path. Thus, the energy of the feeding source FD can flow in the first and second inductive paths, so as to reduce the capacitive effect between the radiation element (the first inverted-F antenna resonant element 20) and the grounding portion 40 through the self-inductance of each of the two inductive paths and the mutual inductance between them.

[0163] Referring to Figure 11, is a three-dimensional schematic diagram of the tenth embodiment of the antenna module 10 of the present invention. In the tenth embodiment of the antenna module 10, the antenna module 10 includes a first inverted-F antenna resonant element 20, an inductance circuit 30, and a substrate 100. The first radiation section 21 of the first inverted-F antenna resonant element 20 includes a first main section 22, two feeding sections FA1 and FA2, and a first short-circuit section 24. Each feeding section has a feeding point. For example, the feeding section FA1 has a feeding point FF1, and the feeding section FA2 has a feeding point FF2. Specifically, the aforementioned first feeding section 23 can be one of the two feeding sections FA1 and FA2, and the other of the two feeding sections FA1 and FA2 is used as a third feeding section having a third feeding point.

[0164] The two feeding sections FA1 and FA2 are connected to the first main section 22. The feeding point of one of the two feeding sections FA1 and FA2 is connected to one of the two ends (i.e., the first end E1 and the second end E2) of the first inductive path of the inductance circuit 30, and the feeding point of the other of the two feeding sections FA1 and FA2 is connected to the other of the two ends (i.e., the first end E1 and the second end E2) of the first inductive path of the inductance circuit 30. For example, as Figure 11 shown, the feeding point FF1 of the feeding section FA1 is connected to the feeding source FD and the second end E2 of the first inductive path of the inductance circuit 30 via a feeding conductive line segment 50. Thus, both the feeding point FF1 and the feeding source FD are connected to the second end E2 of the first inductive path via the feeding conductive line segment 50. The feeding point FF2 of the feeding section FA2 is connected to the first end E1 of the first inductive path of the inductance circuit 30.

[0165] Specifically, the second end E2 of the first inductive path of the inductance circuit 30 is connected to the feeding source FD via a feeding conductive line segment 50. The feeding conductive line segment 50 extends a length from the inductance circuit 30 along a direction parallel to the edge of the grounding portion 40 (specifically, along a linear grounding conductive line segment 41 parallel to the grounding portion 40, such as along the horizontal direction), and the end of the feeding conductive line segment 50 is connected to the feeding source FD. The feeding point FF1 of the feeding section FA1 is connected to the end of the feeding conductive line segment 50. Thus, both the feeding point FF1 and the feeding source FD are connected to the second end E2 of the first inductive path via the feeding conductive line segment 50. The feeding section FA1 extends a length from the end of the feeding conductive line segment 50 in a direction away from the grounding portion 40 (such as along the vertical direction), and the end of the feeding section FA1 is connected to the first main section 22. The feeding section FA2 extends a length from the inductance circuit 30 along a direction parallel to the feeding section FA1, and the end of the feeding section FA2 is connected to the first main section 22. The first main section 22 extends a length along a direction parallel to the feeding conductive line segment 50, and the ends of the two feeding sections FA1 and FA2 are connected to a region between the two ends of the first main section 22.

[0166] The first short - circuit section 24 is connected to one of the two - feed sections FA1 and FA2 (for example, the end of the third section 243 of the first short - circuit section 24 is connected to the area between the two ends of one of the two - feed sections FA1 and FA2). The first short - circuit point S1 and the grounding portion 40 are respectively connected to the two ends of the second inductive path (i.e., are respectively connected to different ends of the second inductive path). For example, the fourth end E4 of the second inductive path of the inductive circuit 30 is connected to the grounding wire segment 41 of the grounding portion 40, and the first short - circuit point S1 is connected to the third end E3 of the second inductive path of the inductive circuit 30. In this way, the antenna module 10 can satisfy the impedance matching required in different scenarios, and the first radiation section 21 can excite the first resonance band, the second resonance band, and the third resonance band. In some exemplary embodiments, there is a distance between the two - feed sections FA1 and FA2 in the horizontal direction.

[0167] As Figure 11 shown, the first short - circuit point S1 of the first inverted - F antenna resonant element 20 and the grounding portion 40 are respectively connected to the two ends of the second inductive path. Therefore, after the energy of the feeding source FD flows through the first inductive path to the first inverted - F antenna resonant element 20, it flows to the grounding portion 40 through the second inductive path. In this way, the energy of the feeding source FD can flow in the first and second inductive paths, thereby reducing the capacitive effect between the radiation element (the first inverted - F antenna resonant element 20) and the grounding portion 40 through the self - inductance of each of the two inductive paths and the mutual inductance between them.

[0168] As Figures 2 to 4 and Figures 8 to 11 shown, in some exemplary embodiments, the first main section 22 has a constant - width structure. As Figures 5 to 7 shown, in other exemplary embodiments, the first main section 22 has a non - constant - width structure. For example, the width at the end of the first main section 22 can be greater than or less than other regions of the first main section 22.

[0169] In the foregoing embodiments, the feeding source FD can be connected to the wireless communication module of the main board through a coaxial cable (specifically, its inner core wire and braided wire). In this way, the wireless communication module can transmit wireless signals through the antenna module 10. The wireless communication module can be a wireless communication circuit having wireless communication certifications (such as Wi - Fi), Bluetooth, and other wireless transmission functions.

[0170] In the foregoing embodiments, the foregoing grounding portion 40, first inverted-F antenna resonant element 20, feeding wire segment 50, first parasitic element 60, second inverted-F antenna resonant element 70, second parasitic element 80, and monopole antenna element 90 are located on the same surface (e.g., the top surface) of the substrate 100. The foregoing grounding portion 40, first inverted-F antenna resonant element 20, feeding wire segment 50, first parasitic element 60, second inverted-F antenna resonant element 70, second parasitic element 80, and monopole antenna element 90 are made of a conductive material. The conductive material may specifically be a conductive layer on the surface of the substrate 100. For example, the foregoing grounding portion 40, first inverted-F antenna resonant element 20, feeding wire segment 50, first parasitic element 60, second inverted-F antenna resonant element 70, second parasitic element 80, and monopole antenna element 90 are formed by patterning the conductive layer laid on the substrate 100. In some exemplary embodiments, the conductive layer patterning may be performed by a certain manufacturing method (e.g., etching), but the present invention is not limited thereto. In the foregoing embodiments, the impedance matching of the entire antenna module 10 may be adjusted by adjusting the dimensions of the internal regions of the foregoing grounding portion 40, first inverted-F antenna resonant element 20, feeding wire segment 50, first parasitic element 60, second inverted-F antenna resonant element 70, second parasitic element 80, and monopole antenna element 90. In the foregoing embodiments, the impedance matching of the entire antenna module 10 may be adjusted by adjusting the dimensions of the foregoing coupling gaps (such as the first coupling gap CG1 to the fifth coupling gap CG5). In some embodiments, if the thickness of the foregoing conductive layer reaches a certain level to provide support strength to maintain its shape, the antenna module 10 may not have the substrate 100.

[0171] Referring to Figure 12 and Figure 13 . Figure 12 is a perspective schematic view of the first embodiment of the inductive circuit 30 of the present invention. Figure 13A side view schematic diagram of the first embodiment of the inductor circuit 30 of the present invention is shown below. The architecture of the inductor circuit 30 will be described with multiple embodiments. In the first embodiment of the inductor circuit 30, the first inductor unit 31 includes a first coil CL1 to implement a first inductive path, and the second inductor unit 32 includes a second coil CL2 to implement a second inductive path. The two ends of the first coil CL1 are the first end E1 and the second end E2 respectively. The two ends of the second coil CL2 are the third end E3 and the fourth end E4 respectively. The first coil CL1 provides a first self-inductance, the second coil CL2 provides a second self-inductance, and the first coil CL1 and the second coil CL2 are mutually coupled to generate a mutual inductance. By the first self-inductance, the second self-inductance, and the mutual inductance, the capacitive effect between the first main section 22 of the first radiation section 21 and the ground portion 40 can be reduced, and the capacitive effect between the second main section 72 of the second radiation section 71 and the ground portion 40 can be reduced. Thus, when the antenna height is reduced (i.e., in a low posture, for example, the distance between the first main section 22 and the ground portion 40 is less than or equal to 5 mm and / or the distance between the second main section 72 and the ground portion 40 is less than or equal to 5 mm), the antenna module 10 can still have good bandwidth and antenna characteristics.

[0172] Continuing, the inductance values of the first self-inductance and the second self-inductance can be respectively between 0.1 nanohenry (nH) and 10 nH. The inductance value of the mutual inductance between the first inductor unit 31 and the second inductor unit 32 can be between 0.1 nH and 5 nH. In a demonstration example, when the antenna module 10 excites the third resonance frequency band, the inductance value of the first self-inductance can be 2.23 nH, the inductance value of the second self-inductance can be 1.8 nH, and the inductance value of the mutual inductance can be 0.62 nH. When the antenna module 10 excites the second resonance frequency band, the inductance value of the first self-inductance can be 2.28 nH, the inductance value of the second self-inductance can be 1.85 nH, and the inductance value of the mutual inductance can be 0.62 nH. When the antenna module 10 excites the third resonance frequency band, the inductance value of the first self-inductance can be 2.59 nH, the inductance value of the second self-inductance can be 2.12 nH, and the inductance value of the mutual inductance can be 0.66 nH. By adjusting the inductance values of the first self-inductance, the second self-inductance, and the mutual inductance, the overall impedance matching of the antenna module 10 can be adjusted.

[0173] Continuing further, the first coil CL1 has at least one first coil turn, and the second coil CL2 has at least one second coil turn. Here, two first coil turns CL1N_1 and CL1N_2 and two second coil turns CL2N_1 and CL2N_2 are shown, but the present invention is not limited thereto, and the number of the first coil turns and the second coil turns can be adjusted according to design requirements. There is a turn spacing GN between adjacent first coil turns and second coil turns, so that the first coil CL1 and the second coil CL2 can be mutually coupled to generate a mutual inductance. As Figure 13 shown, the first coil turn CL1N_2 is adjacent to the second coil turn CL2N_1, and there is a turn spacing GN between them.

[0174] Refer to Figure 12 、 Figure 13 and Figure 14 。 Figure 14 is a perspective schematic view of the second embodiment of the inductor circuit 30 of the present invention. As Figure 12 and Figure 13 shown, in the first embodiment of the inductor circuit 30, the first coil CL1 and the second coil CL2 are wound with square wires. As Figure 14 shown, the difference from the first embodiment of the inductor circuit 30 is that in the second embodiment of the inductor circuit 30, the first coil CL1 and the second coil CL2 are wound with round wires.

[0175] Refer to Figure 15 , which is a perspective schematic view of the third embodiment of the inductor circuit 30 of the present invention. The difference from the second embodiment of the inductor circuit 30 is that in the third embodiment of the inductor circuit 30, the first coil turns and the second coil turns are arranged alternately. For example, one first coil turn is sandwiched between every two second coil turns. As Figure 15 shown, one first coil turn CL1N_2 is sandwiched between two second coil turns CL2N_1 and CL2N_2. Specifically, the arrangement order of the first coil turns CL1N_1, CL1N_2 and the second coil turns CL2N_1, CL2N_2 is "first coil turn CL1N_1, second coil turn CL2N_1, first coil turn CL1N_2, second coil turn CL2N_2... etc.". In this way, the first coil turn CL1N_1 and the second coil turn CL2N_1 are adjacent to each other and spaced by a turn pitch GN1, the second coil turn CL2N_1 and the first coil turn CL1N_2 are adjacent to each other and spaced by a turn pitch GN2, and the first coil turn CL1N_2 and the second coil turn CL2N_2 are adjacent to each other and spaced by a turn pitch GN3. In some exemplary cases, the turn pitches GN1, GN2, GN3 between these first coil turns CL1N_1, CL1N_2 and these second coil turns CL2N_1, CL2N_2 can have the same size. However, the present invention is not limited to this. In other exemplary cases, the turn pitches GN1, GN2, GN3 can have different sizes.

[0176] Refer to Figure 16 , which is a perspective schematic view of the fourth embodiment of the inductor circuit 30 of the present invention. In the fourth embodiment of the inductor circuit 30, the inductor circuit 30 further includes a sealing body 33 that covers the first coil CL1 and the second coil CL2. Although Figures 12 to 15 not shown, however, the inductor circuit 30 in the first to third embodiments of the inductor circuit 30 may also include a sealing body 33 that covers the first coil CL1 and the second coil CL2. As Figure 15As shown, in the third embodiment of the inductance circuit 30, the first coil CL1 and the second coil CL2 are wound with round wires. As Figure 16 shown, the difference from the third embodiment of the inductance circuit 30 is that in the fourth embodiment of the inductance circuit 30, the first coil CL1 and the second coil CL2 are wound with square wires. In some exemplary cases, the sealing body 33 can be formed of an insulating material, such as FR4 glass fiber, ceramic, strontium titanate (SrTiO3), titanium dioxide (TiO2), barium titanate (BaTiO3), etc.

[0177] In the first, second, third, and fourth embodiments of the inductance circuit 30, the turn spacings GN, GN1, GN2, GN3 can be in the range of 0.15 mm or less. The turn spacings GN, GN1, GN2, GN3 can be adjusted according to requirements, and this should not be taken as a limit. In the first, second, third, and fourth embodiments of the inductance circuit 30, the first coil CL1 and the second coil CL2 overlap. Specifically, the first coil CL1 and the second coil CL2 have the same winding axis. That is to say, the first coil CL1 and the second coil CL2 are wound based on the same winding axis.

[0178] Referring to Figure 17 , it is a perspective schematic diagram of the fifth embodiment of the inductance circuit 30 of the present invention. The difference from the first embodiment of the inductance circuit 30 is that in the fifth embodiment of the inductance circuit 30, the first coil CL1 and the second coil CL2 do not overlap or partially overlap. Specifically, there is a first distance R between the winding axis C1 around which the first coil CL1 is wound and the winding axis C2 around which the second coil CL2 is wound. In some exemplary cases, the first distance R is not greater than the sum of the winding radius R1 of the first coil CL1 and the winding radius R2 of the second coil CL2, as shown in Equation 1. The winding radius R1 is the distance from the winding axis C1 of the first coil CL1 to one end of the first coil CL1 (i.e., the first end E1 or the second end E2). The winding radius R2 is the distance from the winding axis C2 of the second coil CL2 to one end of the second coil CL2 (i.e., the third end E3 or the fourth end E4). In some exemplary cases, the sum of the winding radius R1 of the first coil CL1 and the winding radius R2 of the second coil CL2 can be 4 mm. In some exemplary cases, there is a second distance GV between the adjacent ends of the first coil CL1 and the second coil CL2 (i.e., between the first end E1 and the fourth end E4). In some exemplary cases, the second distance GV is in the range of 1.5 mm or less, as shown in Equation 2.

[0179] 0 mm ≤ R ≤ R1 + R2 ………………… (Equation 1)

[0180] 0 mm ≤ GV ≤ 1.5 mm ………………… (Equation 2)

[0181] Referring to Figure 18 , which is a perspective schematic view of the sixth embodiment of the inductor circuit 30 of the present invention. In the sixth embodiment of the inductor circuit 30, the first inductor unit 31 of the inductor circuit 30 includes a first inductive segment ML1 to implement a first inductive path. The second inductor unit 32 of the inductor circuit 30 includes a second inductive segment ML2 to implement a second inductive path. The two ends of the first inductive segment ML1 are a first end E1 and a second end E2 respectively. The two ends of the second inductive segment ML2 are a third end E3 and a fourth end E4 respectively. The first inductive segment ML1 provides a first self-inductance, and the second inductive segment ML2 provides a second self-inductance. There is a line spacing g between the first inductive segment ML1 and the second inductive segment ML2, so that the first inductive segment ML1 and the second inductive segment ML2 can be mutually coupled to generate mutual inductance. By means of the first self-inductance, the second self-inductance and the mutual inductance, it is possible to reduce the capacitance effect between the first main section 22 of the first radiation section 21 and the grounding portion 40 and reduce the capacitance effect between the second main section 72 of the second radiation section 71 and the grounding portion 40. In some exemplary cases, the line spacing g between the first inductive segment ML1 and the second inductive segment ML2 can be in the range of 3 mm or less.

[0182] In the sixth embodiment of the inductor circuit 30, the first inductive segment ML1 and the second inductive segment ML2 are conductive layers located on the same surface of the substrate 34. The material of the conductive layer can be carbon fiber, metal or alloy with conductive properties, such as: gold, silver, copper, nickel, palladium alloy, etc. In some exemplary cases, the first inductive segment ML1 and the second inductive segment ML2 are formed by patterning the conductive layer laid on the surface of the substrate 34 by means of dry etching or wet etching, etc. In some exemplary cases, the first inductive segment ML1 and the second inductive segment ML2 are linear and parallel to each other. That is, the distribution shapes of the conductive layers of the first inductive segment ML1 and the second inductive segment ML2 can be linear and parallel to each other respectively.

[0183] Referring to Figure 19 and Figure 20 . Figure 19 which is a perspective schematic view of the seventh embodiment of the inductor circuit 30 of the present invention. Figure 20It is a schematic side cross-sectional view of the seventh embodiment of the inductance circuit 30 of the present invention. The difference from the sixth embodiment of the inductance circuit 30 is that in the seventh embodiment of the inductance circuit 30, the first inductive segment ML1 and the second inductive segment ML2 are respectively located on two opposite planes of the substrate 34. Thus, the line spacing g between the first inductive segment ML1 and the second inductive segment ML2 is the distance between the top surface and the bottom surface of the substrate 34 (i.e., the thickness of the substrate 34). In some exemplary cases, the routing paths of the first inductive segment ML1 and the second inductive segment ML2 are not linear, for example, they are concave and convex respectively. The first inductive segment ML1 and the second inductive segment ML2 respectively have an overlapping section, and the two overlapping sections face each other to mutually couple to generate mutual inductance.

[0184] As Figure 19 and Figure 20 shown, in the seventh embodiment of the inductance circuit 30, the first inductance unit 31 further includes a first inductor I1. The second inductance unit 32 further includes a second inductor I2. The first inductor I1 is connected to the first inductive segment ML1 to jointly realize the first inductive path with the first inductive segment ML1. The second inductor I2 is connected to the second inductive segment ML2 to jointly realize the second inductive path with the second inductive segment ML2. The first inductor I1 and the second inductor I2 are inductor components. Thus, an additional inductance value can be added to strengthen the first self-inductance of the first inductance unit 31 and the second self-inductance of the second inductance unit 32, so as to meet the inductance required for the antenna module 10 to reduce the capacitance effect. In some exemplary cases, the first inductor I1 and the second inductor I2 are located on the same side of the substrate 34. In some exemplary cases, the first inductor I1 and the second inductor I2 and the first inductive segment ML1 are located on the same side of the substrate 34; in other exemplary cases, the first inductor I1 and the second inductor I2 and the second inductive segment ML2 are located on the same side of the substrate 34 (not shown in the figure). As Figure 19 and Figure 20 shown, it is an example where the first inductor I1 and the second inductor I2 and the first inductive segment ML1 are located on the same side of the substrate 34. The lead of the first inductor I1 is directly connected to the first inductive segment ML1, and the lead of the second inductor I2 is indirectly connected to the second inductive segment ML2 via a wire WR passing through the substrate 34.

[0185] In some exemplary embodiments, the first inductor I1 and the second inductor I2 are located on opposite sides (i.e., the first side and the second side) of the substrate 34. For example, the first inductor I1 and the first inductive segment ML1 are located on the same side (the first side) of the substrate 34, and the first inductor I1 is directly connected to the first inductive segment ML1; the second inductor I2 and the second inductive segment ML2 are located on the same side (the second side) of the substrate 34, and the second inductor I2 is directly connected to the second inductive segment ML2.

[0186] In some exemplary embodiments, the inductance values of the first self-inductance and the second self-inductance can be determined by the lengths, widths, and permeabilities of the aforementioned first coil CL1, second coil CL2, first inductive segment ML1, and second inductive segment ML2, as well as the inductance values of the first inductor I1 and the second inductor I2. In some exemplary embodiments, the permeability can be less than 40 times the permeability of free space, where the permeability of free space is 4π×10 -7 H / m (henries per meter). In some exemplary embodiments, the mutual inductance between the first inductance unit 31 and the second inductance unit 32 can be determined by the overlapping area size, turn spacing GN, GN1, GN2, GN3, second distance GV, and line spacing g between the aforementioned first coil CL1 and the second coil CL2.

[0187] In some exemplary embodiments, when applying any of the aforementioned embodiments of the inductance circuit 30 to any of the aforementioned embodiments of the antenna module 10, it is possible to connect the elements of the antenna module, as described in the aforementioned embodiments, to both ends of the first inductive path and both ends of the second inductive path of the inductance circuit 30 by means of additional traces or by adjusting the positions of some of the elements of the antenna module 10.

[0188] Refer to Figures 21 to 23 。 Figure 21 is a perspective view of the antenna module 10_CP of the first comparative example of the present invention. Figure 22 is a perspective view of the antenna module 10_CP of the second comparative example of the present invention. Figure 23It is a three-dimensional schematic diagram of the antenna module 10_CP of the third comparative example of the present invention. In the first comparative example, the antenna height is relatively high, that is, the distance between the first main section 22_CP of the first radiating section 21_CP of the first inverted-F antenna resonant element 20_CP of the antenna module 10_CP and the ground portion 40_CP is relatively large. For example, this distance is 7 mm. In the second comparative example, the antenna height is the second highest. For example, the distance between the first main section 22_CP of the antenna module 10_CP in the second comparative example and the ground portion 40_CP is 6 mm, which is less than the distance between the first main section 22_CP of the antenna module 10_CP in the first comparative example and the ground portion 40_CP. In the third comparative example, the antenna height is relatively low. For example, the distance between the first main section 22_CP of the antenna module 10_CP in the third comparative example and the ground portion 40_CP is 5 mm, which is less than the distance between the first main section 22_CP of the antenna module 10_CP in the second comparative example and the ground portion 40_CP. That is to say, compared with the first and second comparative examples, the third comparative example has a low profile.

[0189] Referring to Figure 24 , it is an experimental data graph of the return loss of the antenna module 10_CP of the first to third comparative examples of the present invention. From Figure 24 , it can be seen that when the antenna height is higher, the antenna module 10_CP has better return loss, that is, there is a positive correlation between the antenna height and the antenna characteristics. For example, the return loss of the antenna module 10_CP in the first comparative example (such as curve CU1) is better than (i.e., less than) the return loss of the antenna module 10_CP in the second comparative example (such as curve CU2), and the return loss of the antenna module 10_CP in the second comparative example is better than (i.e., less than) the return loss of the antenna module 10_CP in the third comparative example (such as curve CU3).

[0190] Referring to Figures 25 to 27 . Figure 25 It is a top view schematic diagram of the antenna module 10_CP of the fourth comparative example of the present invention. Figure 26 It is a bottom view schematic diagram of the antenna module 10_CP of the fourth comparative example of the present invention. Figure 27It is a schematic side cross-sectional view of a partial region A of the antenna module 10_CP of the fourth comparative example of the present invention. The difference from the first embodiment of the antenna module 10 of the present invention is that in the fourth comparative example of the antenna module 10_CP, the antenna module 10_CP does not have an inductive circuit 30. The first short-circuit section 24_CP of the first radiation section 21_CP of the first inverted-F antenna resonant element 20_CP of the antenna module 10_CP is directly connected to the ground wire section 41_CP of the ground portion 40_CP. The first feeding section 23_CP of the first radiation section 21_CP of the first inverted-F antenna resonant element 20_CP of the antenna module 10_CP is connected to the conductive layer 101 on the bottom surface of the substrate 100_CP via the first jumper section JP1, and the conductive layer 101 is connected to the feeding wire section 50_CP on the top surface of the substrate 100_CP via the second jumper section JP2, and the feeding wire section 50_CP is connected to the feeding source FD_CP.

[0191] Referring to Figure 28 , it is an experimental data graph of the return loss of the antenna module 10_CP of the fourth comparative example of the present invention and the first embodiment of the antenna module 10. The curves CU4 and CU5 are the experimental data obtained when both the antenna module 10_CP of the fourth comparative example and the first embodiment of the antenna module 10 are in a low posture. For example, the distance between the first main section 22_CP of the antenna module 10_CP of the fourth comparative example and the ground portion 40_CP is 5 mm, and the distance between the first main section 22 of the first embodiment of the antenna module 10 and the ground portion 40 is also 5 mm. The curve CU4 is the return loss of the antenna module 10_CP of the fourth comparative example. The curve CU5 is the return loss of the first embodiment of the antenna module 10. Compared with the antenna module 10_CP of the fourth comparative example, since the antenna module 10 can reduce the capacitance effect between the first main section 22 and the ground portion 40 by means of the inductive circuit 30 in the first embodiment, the antenna module 10 still has better return loss when the antenna height is relatively low. For example, the return loss of the antenna module 10 in the first embodiment can approach the return loss of the first comparative example.

[0192] Referring to Figure 29, is a perspective schematic diagram of the antenna module 10_CP of the fifth comparative example of the present invention. In the fifth comparative example, the antenna module 10_CP includes a coupled antenna resonant element 11 and an inductive circuit 30_CP. The coupled antenna resonant element 11 includes a first coupling section 111 and a second coupling section 112. The first coupling section 111 and the second coupling section 112 are adjacent and separated by a coupling gap. The first inductive path of the inductive circuit 30_CP is between the feeding source FD_CP and the first coupling section 111, and the second inductive path of the inductive circuit 30_CP is between the second coupling section 112 and the grounding portion 40_CP. Through the coupling gap, the energy of the feeding source FD_CP is coupled from the first coupling section 111 to the second coupling section 112 and passes through the grounding portion 40_CP to form a resonance circuit.

[0193] Referring to Figure 30 , is an experimental data graph of the return loss of the antenna module 10_CP of the fifth comparative example and the first embodiment of the antenna module 10 of the present invention. The curve CU6 and the curve CU7 are the experimental data obtained when both the antenna module 10_CP of the fifth comparative example and the first embodiment of the antenna module 10 are in an environment adjacent to a metal shield. The curve CU6 is the return loss of the antenna module 10_CP of the fifth comparative example. The curve CU6 is the return loss of the first embodiment of the antenna module 10. Compared with the antenna module 10_CP implemented by the coupled antenna resonant element 11 (such as the antenna module 10_CP of the fifth comparative example), the antenna module 10 implemented by the inverted-F antenna resonant element (such as the first embodiment of the antenna module 10) still has better return loss and better antenna characteristics when in an environment adjacent to a metal shield.

[0194] In summary, according to some embodiments, through the inductive circuit, the present invention can reduce the capacitive effect between the first radiation section of the first inverted-F antenna resonant element and the grounding portion while reducing the antenna height (i.e., low profile), so as to improve the bandwidth and antenna characteristics of the antenna module. In some embodiments, in addition to reducing the capacitive effect between the first radiation section of the first inverted-F antenna resonant element and the grounding portion, the inductive circuit of the present invention also reduces the capacitive effect between the second radiation section of the second inverted-F antenna resonant element and the grounding portion, so as to further improve the bandwidth and antenna characteristics of the antenna module. In some embodiments, through the radiation characteristics of the first inverted-F antenna resonant element, the second inverted-F antenna resonant element and other radiation elements (such as parasitic elements, monopole antenna elements, etc.), the antenna module can still have good bandwidth and antenna characteristics when in an environment adjacent to a metal shield (such as the distance from the metal shield is less than 5 mm).
