The following embodiments will further explain the relevant technical content of the present invention in detail, but the disclosed content is not intended to limit the scope of protection of the present invention. In addition, the term "or" used in this article may include any one or more combinations of the associated listed items depending on the actual situation.

[0023] See Figures 1 to 13As shown, the present invention provides a flat antenna module M (or patch antenna module), which includes: an antenna supporting structure 1, an inner ring radiating structure 2, a first inner feeding structure 3, an outer ring radiating structure 5, and a first outer feeding structure 6. Further, the inner ring radiating structure 2 is disposed on the antenna supporting structure 1. The first inner feeding structure 3 is disposed on the antenna supporting structure 1, and the first inner feeding structure 3 is surrounded by the inner ring radiating structure 2. The outer ring radiating structure 5 is disposed on the antenna supporting structure 1, and the inner ring radiating structure 2 is surrounded by the outer ring radiating structure 5 and separated from the outer ring radiating structure 5. The first outer feeding structure 6 is disposed on the antenna supporting structure 1 and corresponds to the first inner feeding structure 3. Thus, the inner annular radiating structure 2 and the first inner feed structure 3 can cooperate with each other to form a first antenna component S1 that can be used for (operated at) a first antenna operating frequency (or a first antenna operating frequency band), and the outer annular radiating structure 5 and the first outer feed structure 6 can cooperate with each other to form a second antenna component S2 that can be used for (operated at) a second antenna operating frequency (or a second antenna operating frequency band). In addition, the first antenna operating frequency of the first antenna component S1 is greater than the second antenna operating frequency of the second antenna component S2. Furthermore, the present invention further provides a portable electronic device D, and the portable electronic device D uses a flat antenna module M.

[0024] [First embodiment]

[0025] See Figures 1 to 5 As shown, a first embodiment of the present invention provides a planar antenna module M, comprising: an antenna supporting 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 a plurality of ground structures 8. For example, the planar antenna module M can be disposed on a circuit substrate P having a plurality of conductive pads (not numbered), 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 example is merely one feasible embodiment and is not intended to limit the present invention.

[0026] Furthermore, cooperation Figures 1 to 4As shown, the inner annular radiating structure 2 is disposed on the antenna supporting structure 1. In addition, the outer annular radiating structure 5 is disposed on the antenna supporting structure 1, and the inner annular radiating structure 2 is surrounded by the outer annular radiating structure 5 and is separated from the outer annular radiating structure 5, so that a surrounding groove is formed between the inner annular radiating structure 2 and the outer annular radiating structure 5. For example, the antenna supporting structure 1 can be a plastic substrate, a ceramic substrate, or any supporting substrate that can be used to support an antenna layout. In addition, the antenna supporting structure 1 can be a hollow supporting structure (or a surrounding supporting structure) having a through-space 100, and the antenna supporting structure 1 has an inner surrounding surface 101 disposed in the through-space 100, an outer surrounding surface 102 surrounding the inner surrounding surface 101, and an upper surface 103 connected between the inner surrounding surface 101 and the outer surrounding surface 102. In addition, the inner annular radiating structure 2 and the outer annular radiating structure 5 are both disposed on the upper surface 103 of the antenna supporting structure 1 (that is, the inner annular radiating structure 2 and the outer annular radiating structure 5 can be coplanarly disposed on the upper surface 103 of the antenna supporting structure 1). Alternatively, the surrounding groove may be formed above the upper surface 103 of the antenna supporting structure 1, or recessed downward from the upper surface 103 of the antenna supporting structure 1. It is worth noting that when a ceramic substrate is used for the antenna supporting structure 1, the multiple ground structures 8 may be omitted. However, the above example is merely one possible embodiment and is not intended to limit the present invention.

[0027] Furthermore, cooperation Figures 1 to 4As shown, the first inner feeding structure 3 is disposed on the antenna supporting structure 1, and the first inner feeding structure 3 is surrounded by the inner ring-shaped radiating structure 2. In addition, the second inner feeding structure 4 is disposed on the antenna supporting structure 1, and the second inner feeding structure 4 is surrounded by the inner ring-shaped radiating structure 2 and is separated from (or adjacent to) the first inner feeding structure 3. For example, the first inner feeding structure 3 includes a first inner horizontal extending portion 31 disposed on the upper surface 103 of the antenna supporting structure 1 and a first inner vertical extending portion 32 (for example, perpendicular to the first inner horizontal extending portion 31) disposed on the inner surrounding surface 101 of the antenna supporting structure 1, and the second inner feeding structure 4 includes a second inner horizontal extending portion 41 disposed on the upper surface 103 of the antenna supporting structure 1 and a second inner vertical extending portion 42 (for example, perpendicular to the second inner horizontal extending portion 41) disposed on the inner surrounding surface 101 of the antenna supporting structure 1. It is noteworthy that the maximum width of the first inner horizontal extension portion 31 is greater than the width of the first inner vertical extension portion 32, and the maximum width of the second inner horizontal extension portion 41 is greater than the width of the second inner vertical extension portion 42. In addition, the first inner feed structure 3 further includes a first inner solder portion (unnumbered) that electrically contacts one of the pads on the circuit substrate P, and the second inner feed structure 4 further includes a second inner solder portion (unnumbered) that electrically contacts another pad on the circuit substrate P. In addition, the first inner feed structure 3 and the second inner feed structure 4 can each be electrically connected to a coupler. However, the above example is only one possible embodiment and is not intended to limit the present invention.

[0028] In addition, with Figures 1 to 4As shown, a first external feeding structure 6 is disposed on the antenna supporting structure 1 and corresponds to the first internal feeding structure 3, and a second external feeding structure 7 is disposed on the antenna supporting structure 1 and corresponds to the second internal feeding structure 4. In addition, the first external feeding structure 6 and the second external feeding structure 7 are separated from each other (or adjacent to each other), and both the first external feeding structure 6 and the second external feeding structure 7 are separated from the outer annular radiating structure 5 by a predetermined distance. For example, the first external feeding structure 6 includes a first outer horizontal extending portion 61 disposed on the outer surrounding surface 102 of the antenna supporting structure 1 and a first outer vertical extending portion 62 disposed on the outer surrounding surface 102 of the antenna supporting structure 1 (e.g., perpendicular to the first outer horizontal extending portion 61), and the second external feeding structure 7 includes a second outer horizontal extending portion 71 disposed on the outer surrounding surface 102 of the antenna supporting structure 1 and a second outer vertical extending portion 72 disposed on the outer surrounding surface 102 of the antenna supporting structure 1 (e.g., perpendicular to the second outer horizontal extending portion 71). It is noteworthy that the width of the first outer horizontal extension portion 61 is greater than the width of the first outer vertical extension portion 62, and the width of the second outer horizontal extension portion 71 is greater than the width of the second outer vertical extension portion 72. Furthermore, the first external feed structure 6 further includes a first external solder portion (unnumbered) that electrically contacts one of the pads on the circuit substrate P, and the second external feed structure 7 further includes a second external solder portion (unnumbered) that electrically contacts another pad on the circuit substrate P. Furthermore, the first external feed structure 6 and the second external feed structure 7 can each be electrically connected to a coupler. However, the above example is merely one possible embodiment and is not intended to limit the present invention.

[0029] In addition, cooperate Figures 1 to 4 As shown, multiple ground structures 8 are disposed in a circumferential manner on the antenna supporting structure 1. Furthermore, the multiple ground structures 8 are separated from one another and are each separated from the outer annular radiating structure 5 by a predetermined distance. For example, the multiple ground structures 8 are disposed in a circumferential manner on the outer circumferential surface 102 of the antenna supporting structure 1 and surround the first inner feed structure 3 and the second inner feed structure 4. It is noteworthy that each ground structure 8 includes a ground solder portion (not numbered) that electrically contacts a corresponding solder pad on the circuit substrate P. However, the above example is merely one possible embodiment and is not intended to limit the present invention.

[0030] For example, with Figures 1 to 4As shown, the inner surrounding surface 101 of the antenna supporting structure 1 has four inner surfaces 1010, and the outer surrounding surface 102 of the antenna supporting structure 1 has four outer surfaces 1020 and four corner edges 1021. Furthermore, the first inner vertical extension portion 32 of the first inner feeding structure 3 and the second inner vertical extension portion 42 of the second inner feeding structure 4 can be respectively disposed on two adjacent inner surfaces 1010 among the four inner surfaces 1010 of the inner surrounding surface 101. In addition, the first outer feeding structure 6 and the second outer feeding structure 7 can be respectively disposed on two adjacent outer surfaces 1020 among the four outer surfaces 1020 of the outer surrounding surface 102. In addition, there are four ground structures 8, and the four ground structures 8 are respectively disposed on the four corner edges 1021 of the outer surrounding surface 102. However, the above example is only one feasible embodiment and is not intended to limit the present invention.

[0031] Thus, 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) cooperate to form a first antenna component 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) cooperate to form a second antenna component S2 for a second antenna operating frequency. The first antenna operating frequency of the first antenna component S1 is greater than the second antenna operating frequency of the second antenna component S2. For example, when the flat panel antenna module M is used in a smartphone, the first antenna operating frequency and the second antenna operating frequency can be 5 GHz and 2.4 GHz, respectively. When the flat panel antenna module M is used in 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 above example is merely one possible embodiment and is not intended to limit the present invention.

[0032] It is worth noting that with Figure 1 and Figure 5 As shown, the first embodiment of the present invention further provides a portable electronic device D, which utilizes a planar antenna module M. Furthermore, the planar antenna module M includes an antenna supporting structure 1, an inner ring radiating structure 2, a first inner feeding structure 3, a second inner feeding structure 4 (which may be omitted), an outer ring radiating structure 5, a first outer feeding structure 6, a second outer feeding 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 above example is merely one possible embodiment and is not intended to limit the present invention.
