Those skilled in the art can understand the advantages and effects of this invention from the content disclosed in this specification. This invention can be implemented or applied through other different specific embodiments, and various details in this specification can also be modified and changed based on different viewpoints and applications without departing from the concept of this invention. Furthermore, the accompanying drawings of this invention are for simple illustration only and are not depictions of actual dimensions, as stated in advance. The following embodiments will further describe the relevant technical content of this invention in detail, but the disclosed content is not intended to limit the scope of protection of this invention. In addition, the term "or" used herein should be interpreted to include, depending on the actual situation, any combination of any one or more of the associated listed items.

[0025] See Figures 1 to 15As shown, the present invention provides a planar antenna module M (or patch antenna module), comprising: an antenna carrier structure 1, an inner ring radiating structure 2, a first inner feed structure 3, an outer ring radiating structure 5, and a first outer feed structure 6. More specifically, the inner ring radiating structure 2 is disposed on the antenna carrier structure 1. The first inner feed structure 3 is disposed on the antenna carrier structure 1 and is surrounded by the inner ring radiating structure 2. The outer ring radiating structure 5 is disposed on the antenna carrier structure 1, and the inner ring radiating structure 2 is surrounded by the outer ring radiating structure 5 but separated from it. The first outer feed structure 6 is disposed on the antenna carrier structure 1 and corresponds to the first inner feed structure 3. The inner ring radiating structure 2 and the outer ring radiating structure 5 are respectively disposed on different planes of the antenna carrier structure 1. Therefore, the inner ring radiating structure 2 and the first inner feed structure 3 can cooperate to form a first antenna assembly S1 that can be used (operated at) a first antenna operating frequency (or a first antenna operating frequency band), and the outer ring radiating structure 5 and the first outer feed structure 6 can cooperate to form a second antenna assembly S2 that can be used (operated at) a second antenna operating frequency (or a second antenna operating frequency band). Furthermore, the first antenna operating frequency of the first antenna assembly S1 is greater than the second antenna operating frequency of the second antenna assembly S2. Moreover, the present invention further provides a portable electronic device D, and the portable electronic device D uses a planar antenna module M.

[0026] [First Embodiment]

[0027] See Figures 1 to 5 As shown, the first embodiment of the present invention provides a planar antenna module M, which includes: an antenna carrying structure 1, an inner ring radiating structure 2, a first inner feed structure 3, a second inner feed structure 4, an outer ring radiating structure 5, a first outer feed structure 6, a second outer feed structure 7, and multiple grounding structures 8. For example, the planar antenna module M can be disposed on a circuit board P, and the circuit board P has multiple conductive pads (unlabeled), and the planar antenna module M can be used as a dual-band circularly polarized planar antenna or multiple single-polarized planar antennas. However, the above examples are merely one feasible embodiment and are not intended to limit the present invention.

[0028] Furthermore, in coordination Figures 1 to 4As shown, the inner annular radiating structure 2 is disposed on the antenna support structure 1. Additionally, the outer annular radiating structure 5 is disposed on the antenna support structure 1, and the inner annular radiating structure 2 is surrounded by and separated from the outer annular radiating structure 5, forming a surrounding groove between the inner annular radiating structure 2 and the outer annular radiating structure 5. For example, the antenna support structure 1 can be a plastic substrate, a ceramic substrate, or any support substrate suitable for supporting an antenna layout. Furthermore, the antenna support structure 1 can be a hollow support structure (or a surrounding support structure) having a through space 100, and the antenna support structure 1 has an inner surrounding surface 101 disposed within the through space 100, an outer surrounding surface 102 surrounding the inner surrounding surface 101, a first upper surface 1031 connected to the inner surrounding surface 101, and a second upper surface 1032 disposed between (or connected to) the first upper surface 1031 and the outer surrounding surface 102. Furthermore, the first upper surface 1031 and the second upper surface 1032 of the antenna support structure 1 have a height difference, and the height of the first upper surface 1031 relative to the circuit board P is "greater" than the height of the second upper surface 1032 relative to the circuit board P. In addition, the inner annular radiating structure 2 and the outer annular radiating structure 5 are respectively disposed on the first upper surface 1031 and the second upper surface 1032 of the antenna support structure 1 (that is, the inner annular radiating structure 2 and the outer annular radiating structure 5 can be disposed non-coplanarly on the first upper surface 1031 and the second upper surface 1032 of the antenna support structure 1), such that the height of the inner annular radiating structure 2 relative to the circuit board P is "greater" than the height of the outer annular radiating structure 5 relative to the circuit board P. Additionally, the surrounding groove can be formed above the upper surface of the antenna support structure 1, or formed by recessing downwards from the upper surface of the antenna support structure 1. It is worth noting that when the antenna support structure 1 uses a ceramic substrate, the multiple grounding structures 8 can be omitted. However, the examples given above are merely one possible embodiment and are not intended to limit the invention.

[0029] Furthermore, cooperation Figures 1 to 4As shown, a first inner feed structure 3 is disposed on the antenna support structure 1 and is surrounded by an inner annular radiating structure 2. Additionally, a second inner feed structure 4 is disposed on the antenna support structure 1 and is surrounded by the inner annular radiating structure 2, and is separate from (or adjacent to) the first inner feed structure 3. For example, the first inner feed structure 3 includes a first inner horizontal extension 31 disposed on the upper surface of the antenna support structure 1 and a first inner vertical extension 32 (e.g., perpendicular to the first inner horizontal extension 31) disposed on the inner surrounding surface 101 of the antenna support structure 1. The second inner feed structure 4 includes a second inner horizontal extension 41 disposed on the upper surface of the antenna support structure 1 and a second inner vertical extension 42 (e.g., perpendicular to the second inner horizontal extension 41) disposed on the inner surrounding surface 101 of the antenna support structure 1. Notably, the maximum width of the first inner horizontal extension 31 is greater than the width of the first inner vertical extension 32, and the maximum width of the second inner horizontal extension 41 is greater than the width of the second inner vertical extension 42. Furthermore, the first internal feed-in structure 3 further includes a first internal solder portion (unlabeled) of one of the solder pads of the electrical contact circuit substrate P, and the second internal feed-in structure 4 further includes a second internal solder portion (unlabeled) of the other solder pad of the electrical contact circuit substrate P. Additionally, the first internal feed-in structure 3 and the second internal feed-in structure 4 can each be electrically connected to a coupler. However, the examples described above are merely one possible embodiment and are not intended to limit the invention.

[0030] In addition, in coordination Figures 1 to 4As shown, the first external feed structure 6 is disposed on the antenna support structure 1 and corresponds to the first internal feed structure 3, and the second external feed structure 7 is disposed on the antenna support structure 1 and corresponds to the second internal feed structure 4. Furthermore, the first external feed structure 6 and the second external feed structure 7 are separated from each other (or adjacent to each other), and both the first external feed structure 6 and the second external feed structure 7 are separated from the outer ring radiation structure 5 by a predetermined distance. For example, the first external feed structure 6 includes a first outer horizontal extension 61 disposed on the outer surrounding surface 102 of the antenna support structure 1 and a first outer vertical extension 62 (e.g., perpendicular to the first outer horizontal extension 61) disposed on the outer surrounding surface 102 of the antenna support structure 1, and the second external feed structure 7 includes a second outer horizontal extension 71 disposed on the outer surrounding surface 102 of the antenna support structure 1 and a second outer vertical extension 72 (e.g., perpendicular to the second outer horizontal extension 71) disposed on the outer surrounding surface 102 of the antenna support structure 1. It is worth noting that the width of the first outer horizontal extension 61 is greater than the width of the first outer vertical extension 62, and the width of the second outer horizontal extension 71 is greater than the width of the second outer vertical extension 72. Furthermore, the first outer feed structure 6 further includes a first outer solder portion (not labeled) of one of the solder pads of the electrical contact circuit substrate P, and the second outer feed structure 7 further includes a second outer solder portion (not labeled) of the other solder pad of the electrical contact circuit substrate P. Moreover, the first outer feed structure 6 and the second outer feed structure 7 can each be electrically connected to a coupler. However, the examples described above are merely one possible embodiment and are not intended to limit the invention.

[0031] In addition, in conjunction with Figures 1 to 4 As shown, a plurality of grounding structures 8 are arranged around the antenna support structure 1. Furthermore, the plurality of grounding structures 8 are separated from each other, and each of the plurality of grounding structures 8 is separated from the outer annular radiating structure 5 by a predetermined distance. For example, the plurality of grounding structures 8 are arranged around the outer annular surface 102 of the antenna support structure 1 and surround the first inner feed structure 3 and the second inner feed structure 4. It is worth noting that each grounding structure 8 includes a grounding solder portion (not labeled) corresponding to a solder pad of an electrical contact circuit board P. However, the examples given above are merely one possible embodiment and are not intended to limit the invention.

[0032] For example, coordination Figures 1 to 4As shown, the inner surrounding surface 101 of the antenna support structure 1 has four inner surfaces 1010, and the outer surrounding surface 102 of the antenna support structure 1 has four outer surfaces 1020 and four corner edges 1021. Furthermore, the first inner vertical extension 32 of the first inner feed structure 3 and the second inner vertical extension 42 of the second inner feed structure 4 can be respectively disposed on two adjacent inner surfaces 1010 of the four inner surfaces 1010 of the inner surrounding surface 101. Additionally, the first outer feed structure 6 and the second outer feed structure 7 can be respectively disposed on two adjacent outer surfaces 1020 of the four outer surfaces 1020 of the outer surrounding surface 102. Moreover, there are four grounding structures 8, and the four grounding structures 8 are respectively disposed on the four corner edges 1021 of the outer surrounding surface 102. However, the examples described above are merely one possible embodiment and are not intended to limit the invention.

[0033] For example, in another feasible embodiment, the antenna support structure 1 may include an inner annular substrate (unlabeled) having a first upper surface 1031 and an outer annular substrate (unlabeled) having a second upper surface 1032, the inner annular substrate being surrounded by the outer annular substrate, and the inner and outer annular substrates having different dielectric constants. However, the examples given above are merely feasible embodiments and are not intended to limit the present invention.

[0034] Therefore, at least the inner ring radiating structure 2, the first inner feed structure 3, and the second inner feed structure 4 (which may be omitted) are used in combination to form a first antenna assembly S1 for a first antenna operating frequency, and at least the outer ring radiating structure 5, the first outer feed structure 6, and the second outer feed structure 7 (which may be omitted) are used in combination to form a second antenna assembly S2 for a second antenna operating frequency, and the first antenna operating frequency of the first antenna assembly S1 is greater than the second antenna operating frequency of the second antenna assembly S2. Therefore, the planar antenna module M provided by the present invention has antenna characteristics of high gain and low axial ratio. For example, when the planar antenna module M is applied to a smartphone, the first antenna operating frequency and the second antenna operating frequency can be 5 GHz and 2.4 GHz, respectively. When the planar antenna module M is applied to a GPS antenna receiver, the first antenna operating frequency and the second antenna operating frequency can be 1.575 GHz and 1.227 GHz, respectively. However, the examples given above are only one possible embodiment and are not intended to limit the present invention.

[0035] It is worth noting that, in conjunction with Figure 1 and Figure 5As shown, the first embodiment of the present invention further provides a portable electronic device D, and the portable electronic device D uses a planar antenna module M. The planar antenna module M includes an antenna carrying structure 1, an inner ring radiating structure 2, a first inner feed structure 3, a second inner feed structure 4 (which may be omitted), an outer ring radiating structure 5, a first outer feed structure 6, a second outer feed structure 7 (which may be omitted), and multiple grounding structures 8. For example, the portable electronic device D may be a laptop computer, a tablet computer, a smartphone, or a GPS antenna receiver. However, the examples given above are merely one possible embodiment and are not intended to limit the present invention.

[0036] [Second Embodiment]

[0037] See Figures 6 to 9 As shown, the second embodiment of the present invention provides a planar antenna module M, which includes: an antenna carrying structure 1, an inner ring radiating structure 2, a first inner feed structure 3, a second inner feed structure 4, an outer ring radiating structure 5, a first outer feed structure 6, a second outer feed structure 7, and multiple grounding structures 8. Figures 6 to 9 respectively with Figures 1 to 4 A comparison reveals that the most significant difference between the second embodiment and the first embodiment of the present invention lies in the following: In the second embodiment, the height of the first upper surface 1031 relative to the circuit substrate P is "less" than the height of the second upper surface 1032 relative to the circuit substrate P. Consequently, the inner annular radiating structure 2 and the outer annular radiating structure 5 are respectively disposed on the first upper surface 1031 and the second upper surface 1032 of the antenna support structure 1 (that is, the inner annular radiating structure 2 and the outer annular radiating structure 5 can be disposed non-coplanarly on the first upper surface 1031 and the second upper surface 1032 of the antenna support structure 1), so that the height of the inner annular radiating structure 2 relative to the circuit substrate P is "less" than the height of the outer annular radiating structure 5 relative to the circuit substrate P.

[0038] [Third Embodiment]

[0039] See Figure 10 and Figure 11 As shown, the third embodiment of the present invention provides a planar antenna module M, which includes: an antenna carrying structure 1, an inner ring radiating structure 2, a first inner feed structure 3, a second inner feed structure 4, an outer ring radiating structure 5, a first outer feed structure 6, a second outer feed structure 7, and multiple grounding structures 8. Figure 10 and Figure 3 The comparison, and Figure 11 and Figure 4A comparison reveals that the most significant difference between the third embodiment and the first embodiment of the present invention lies in the following: In the third embodiment, the antenna support structure 1 has an inner surrounding surface 101 disposed within the through space 100, an outer surrounding surface 102 surrounding the inner surrounding surface 101, an upper surface 103 connecting the inner surrounding surface 101 and the outer surrounding surface 102, a surrounding space 104 formed between the inner surrounding surface 101 and the outer surrounding surface 102, and a lower surface 105 disposed within the surrounding space 104 and corresponding to the upper surface 103. Furthermore, the inner annular radiating structure 2 is disposed on the lower surface 105 of the antenna support structure 1, and the outer annular radiating structure 5 is disposed on the upper surface 103 of the antenna support structure 1 (that is, the inner annular radiating structure 2 and the outer annular radiating structure 5 can be non-coplanarly disposed on the antenna support structure 1). It is noteworthy that the height difference between the inner annular radiating structure 2 and the outer annular radiating structure 5 can be determined by the thickness of the antenna support structure 1 (i.e., the distance between the upper surface 103 and the lower surface 105).

[0040] [Fourth Embodiment]

[0041] See Figure 12 and Figure 13 As shown, the fourth embodiment of the present invention provides a planar antenna module M, which includes: an antenna carrying structure 1, an inner ring radiating structure 2, a first inner feed structure 3, a second inner feed structure 4, an outer ring radiating structure 5, a first outer feed structure 6, a second outer feed structure 7, and multiple grounding structures 8. Figure 12 and Figure 3 The comparison, and Figure 13 and Figure 4 A comparison reveals that the most significant difference between the fourth embodiment and the first embodiment of the present invention lies in the following: In the fourth embodiment, the antenna support structure 1 has an inner surrounding surface 101 disposed within the through space 100, an outer surrounding surface 102 surrounding the inner surrounding surface 101, an upper surface 103 connecting the inner surrounding surface 101 and the outer surrounding surface 102, a surrounding space 104 formed between the inner surrounding surface 101 and the outer surrounding surface 102, and a lower surface 105 disposed within the surrounding space 104 and corresponding to the upper surface 103. Furthermore, the inner annular radiating structure 2 is disposed on the upper surface 103 of the antenna support structure 1, and the outer annular radiating structure 5 is disposed on the lower surface 105 of the antenna support structure 1 (that is, the inner annular radiating structure 2 and the outer annular radiating structure 5 can be non-coplanarly disposed on the antenna support structure 1). It is noteworthy that the height difference between the inner annular radiating structure 2 and the outer annular radiating structure 5 can be determined by the thickness of the antenna support structure 1 (i.e., the distance between the upper surface 103 and the lower surface 105).

[0042] It is worth noting that, for example, in another feasible embodiment, the antenna support structure 1 may have a first lower surface (not shown) and a second lower surface (not shown), and the first lower surface and the second lower surface of the antenna support structure 1 have a height difference. Therefore, when the inner annular radiating structure 2 and the outer annular radiating structure 5 are respectively disposed on the first lower surface and the second lower surface of the antenna support structure 1, the inner annular radiating structure 2 and the outer annular radiating structure 5 may be disposed on the first lower surface and the second lower surface of the antenna support structure 1 respectively and non-coplanarly. However, the examples given above are only one feasible embodiment and are not intended to limit the present invention.

[0043] [Fifth Embodiment]

[0044] See Figure 14 and Figure 15 As shown, the fifth embodiment of the present invention provides a flat panel antenna module M, which includes: an antenna carrying structure 1, an inner ring radiating structure 2, a first inner feed structure 3, a second inner feed structure 4, an outer ring radiating structure 5, a first outer feed structure 6, a second outer feed structure 7, and multiple grounding structures 8. Figure 14 and Figure 3 The comparison, and Figure 15 and Figure 4A comparison reveals that the most significant difference between the fifth embodiment and the first embodiment of the present invention lies in the following: In the fifth embodiment, the antenna support structure 1 can be a solid support structure without a through space, and the antenna support structure 1 has an outer surrounding surface 102, a first upper surface 1031, and a second upper surface 1032 disposed between (or connected to) the first upper surface 1031 and the outer surrounding surface 102, and the first upper surface 1031 and the second upper surface 1032 of the antenna support structure 1 have a height difference. Furthermore, the inner annular radiating structure 2 and the outer annular radiating structure 5 are respectively disposed on the first upper surface 1031 and the second upper surface 1032 of the antenna support structure 1, and the height of the first upper surface 1031 relative to the circuit board P is "greater" than the height of the second upper surface 1032 relative to the circuit board P. Furthermore, the inner annular radiating structure 2 and the outer annular radiating structure 5 are respectively disposed on the first upper surface 1031 and the second upper surface 1032 of the antenna support structure 1 (that is, the inner annular radiating structure 2 and the outer annular radiating structure 5 can be disposed on the first upper surface 1031 and the second upper surface 1032 of the antenna support structure 1 in a non-coplanar manner), so that the height of the inner annular radiating structure 2 relative to the circuit board P is "greater" than the height of the outer annular radiating structure 5 relative to the circuit board P. More specifically, the first inner feed structure 3 includes a first inner horizontal extension portion 31 disposed on the upper surface of the antenna support structure 1 and a first inner vertical extension portion 32 penetrating the antenna support structure 1, and the second inner feed structure 4 includes a second inner horizontal extension portion 41 disposed on the upper surface of the antenna support structure 1 and a second inner vertical extension portion 42 penetrating the antenna support structure 1.

[0045] It is worth noting that, for example, in another feasible embodiment, the height of the first upper surface 1031 relative to the circuit board P can be "less" than the height of the second upper surface 1032 relative to the circuit board P. Thereby, the inner annular radiating structure 2 and the outer annular radiating structure 5 are respectively disposed on the first upper surface 1031 and the second upper surface 1032 of the antenna support structure 1 (that is, the inner annular radiating structure 2 and the outer annular radiating structure 5 can be disposed non-coplanarly on the first upper surface 1031 and the second upper surface 1032 of the antenna support structure 1), such that the height of the inner annular radiating structure 2 relative to the circuit board P is "less" than the height of the outer annular radiating structure 5 relative to the circuit board P. However, the examples given above are merely one feasible embodiment and are not intended to limit the present invention.

[0046] [Beneficial Effects of the Examples]

Furthermore, the first antenna operating frequency of the first antenna assembly S1 is greater than the second antenna operating frequency of the second antenna assembly S2.

[0048] It is worth noting that the planar antenna module M provided by the present invention has antenna characteristics of high gain and low axial ratio.
