[0044] Reference will now be made in detail to exemplary embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same element symbols are used in the drawings and description to denote the same or similar parts.

[0045] Please refer to Figure 1 , Figure 1This is a schematic diagram of an antenna architecture according to an embodiment of the present invention. The antenna architecture 100 includes a first signal source S1, a second signal source S2, a first radiator 101, a second radiator 102, a third radiator 103, a first circuit 104, and a second circuit 105. The first signal source S1 generates a first signal, and the second signal source S2 generates a second signal. The first radiator 101 is coupled to the first signal source S1 to receive the first signal, and the second radiator 102 is coupled to the second signal source S2 to receive the second signal. The first circuit 104 has a first terminal coupled to the third radiator 103, and the second circuit 105 has a first terminal coupled to the third radiator 103. The second terminal of the first circuit 104 can be coupled to either the first radiator 101 or the first signal source S1. The second terminal of the second circuit 105 can be coupled to either the second radiator 102 or the second signal source S2.

[0046] In this embodiment, when the second terminal of the first circuit 104 is coupled to the first radiator 101, the second terminal of the second circuit 105 can be coupled to the second radiator 102. When the second terminal of the first circuit 104 is coupled to the first signal source S1, the second terminal of the second circuit 105 can be coupled to the second signal source S2.

[0047] The first circuit 104 and the second circuit 105 of the present invention each have a switching function, and may also have impedance matching and / or filtering functions. When the second terminal of the first circuit 104 is coupled to the first radiator 101, the first circuit 104 can, through its switching function, connect or disconnect the connection path between the first radiator 101 and the third radiator 103. Conversely, when the second terminal of the second circuit 105 is coupled to the second radiator 102, the second circuit 105 can, through its switching function, connect or disconnect the connection path between the second radiator 102 and the third radiator 103. On the other hand, when the second terminal of the first circuit 104 is coupled to the first signal source S1, the first circuit 104 can, through its switching function, connect or disconnect the connection path between the first signal source S1 and the third radiator 103. Conversely, when the second terminal of the second circuit 105 is coupled to the second signal source S2, the second circuit 105 can, through its switching function, connect or disconnect the connection path between the second signal source S2 and the third radiator 103. The first circuit 104 and the second circuit 105 described above can switch according to the mode selection signal MD so that the antenna architecture 100 can operate in different modes.

[0048] The first to third radiators 101-103 can be constructed of conductive structures, thus generating radiated signals by means of changes in the current distribution on the conductive structures over time. The conductive structures constituting the first to third radiators 101-103 can be implemented using antenna structure designs well-known to those skilled in the art, without fixed limitations. In some embodiments, the first to third radiators 101-103 can be part of the metal casing of an electronic device.

[0049] In some embodiments, none of the first to third radiators 101-103 are coupled to the reference ground terminal of the electronic device. In some embodiments, each of the first to third radiators 101-103 may also have one end coupled to the reference ground terminal of the electronic device on which the antenna architecture 100 is disposed. In some embodiments, only the third radiator 103 has one end coupled to the reference ground terminal of the electronic device. Furthermore, in some specific embodiments, the third radiator 103 may also be constituted as an extension structure of the main ground plane of the electronic device.

[0050] Furthermore, the first signal source S1 and the second signal source S2 can be composed of circuits, or can be the transmission terminal (Transmit, Tx) of the electronic device provided in the antenna architecture 100, or can be the Tx terminal of an external device, or can be any known form of signal source, used to provide signals to excite the radiator to generate radiation signals.

[0051] Please refer to Figure 2 as well as Figure 1 , Figure 2 The present invention is shown. Figure 1 Schematic diagrams of the first and second circuits in the embodiment. Wherein, Figure 1 In the embodiments, the first circuit 104 and the second circuit 105 may have the same circuit architecture. For example... Figure 2 The circuit 200 shown in the figure includes a switching circuit 210, a filtering circuit 220, and an impedance matching circuit 230. The switching circuit 210, filtering circuit 220, and impedance matching circuit 230 are connected in series and coupled to each other. Circuit 200 may have a first terminal ED1 and a second terminal ED2. The connection order of the switching circuit 210, filtering circuit 220, and impedance matching circuit 230 is not fixed. Figure 2 The illustrations are merely examples for illustrative purposes and are not intended to limit the scope of the invention.

[0052] exist Figure 2In this circuit, switching circuit 210 is used to turn on or off the connection between the first terminal ED1 and the second terminal ED2 of circuit 200 according to the mode selection signal MD. Filtering circuit 220 is used to filter the received signal when switching circuit 210 is on. Impedance matching circuit 230 is used to ensure that the impedances of the two connected circuits are matched when switching circuit 210 is on.

[0053] The hardware architecture of the switching circuit 210, the filtering circuit 220, and the impedance matching circuit 230 can all be implemented using circuit structures familiar to those skilled in the art, without any fixed limitations.

[0054] Please refer to Figure 3 , Figure 3 This is a schematic diagram illustrating an embodiment of a common mode of the antenna architecture of the present invention. The antenna architecture 300 includes a first signal source S1, a second signal source S2, a first radiator 301, a second radiator 302, a third radiator 303, a first circuit 304, a second circuit 305, and impedance matching circuits 306 and 307. The first circuit 304 is coupled between the first radiator 301 and the third radiator 303, and the second circuit 305 is coupled between the second radiator 302 and the third radiator 303. Figure 1 The difference in the embodiment is that the impedance matching circuit 306 is coupled between the first radiator 301 and the first signal source S1 to perform impedance matching between the first radiator 301 and the first signal source S1; the impedance matching circuit 307 is coupled between the second radiator 302 and the second signal source S2 to perform impedance matching between the second radiator 302 and the second signal source S2.

[0055] In this embodiment, in the shared mode, based on the selection of the mode selection signal MD, the first circuit 304 can connect the first radiator 301 and the third radiator 303. In this way, the first signal generated by the first signal source S1 can be transmitted to the first radiator 301, and through the first circuit 304, the first signal can be further provided to the third radiator 303. On the other hand, the second circuit 305 disconnects the connection between the second radiator 302 and the third radiator 303 according to the mode selection signal MD, preventing the second signal generated by the second signal source S2 from being provided to the third radiator 303. Through the selection of the mode selection signal MD, the third radiator 303 and the first radiator 301 form a first sub-antenna structure A1, which can jointly receive the first signal. The second signal generated by the second signal source S2 is only provided to the second radiator 302. The second radiator 302 can form a second sub-antenna structure A2. The antenna architecture 300 of the present invention can adjust the radiation pattern of the antenna structure 300 by sharing the first radiator 301 and the third radiator 303 in the first sub-antenna architecture A1.

[0056] Please refer to Figure 4 , Figure 4 This is a schematic diagram of another common mode embodiment of the antenna architecture of the present invention. The antenna architecture 400 includes a first signal source S1, a second signal source S2, a first radiator 401, a second radiator 402, a third radiator 403, a first circuit 404, a second circuit 405, and impedance matching circuits 406 and 407. Figure 3 The difference in the embodiment is that the first circuit 404 is coupled between the first signal source S1 and the third radiator 403, and the second circuit 405 is coupled between the second signal source S2 and the third radiator 403.

[0057] In this embodiment, in the shared mode, based on the selection of the mode selection signal MD, the first circuit 404 connects the first signal source S1 and the third radiator 403. Thus, the first signal generated by the first signal source S1 can be transmitted to the first radiator 401, and through the first circuit 404, the first signal can be provided to the third radiator 403. On the other hand, the second circuit 405 disconnects the connection between the second signal source S2 and the third radiator 403 according to the mode selection signal MD, preventing the second signal generated by the second signal source S2 from being provided to the third radiator 403. Through the selection of the mode selection signal MD, the third radiator 403 and the first radiator 401 form a first sub-antenna architecture A1, and can jointly receive the first signal generated by the first signal source S1. The second signal generated by the second signal source S2 is only provided to the second radiator 402. The second radiator 402 can form a second sub-antenna architecture A2. The antenna architecture 400 of the present invention can adjust the radiation pattern of the antenna structure 400 by sharing the first radiator 401 and the third radiator 403 in the first sub-antenna architecture A1.

[0058] Please refer to Figure 5 , Figure 5 This is a schematic diagram of another antenna architecture embodiment of the present invention. The antenna architecture 500 includes a first signal source S1, a second signal source S2, a first radiator 501, a second radiator 502, a third radiator 503, a first circuit 504, a second circuit 505, a third circuit 506, and a fourth circuit 507. Figure 4 The difference in this embodiment lies in that the third circuit 506 is coupled between the first radiator 501 and the first signal source S1, and the fourth circuit 507 is coupled between the second radiator 502 and the first signal source S2. Each of the third circuit 506 and the fourth circuit 507 has a switching function, and may also have impedance matching and / or filtering functions. In this embodiment, the third circuit 506 and the fourth circuit 507 may be circuits with the same architecture as the first circuit 504 and the second circuit 505, but... Figure 2 The circuit architecture illustrated in circuit 200.

[0059] The third circuit 506 can switch the connection path between the first radiator 501 and the first signal source S1 to be connected or disconnected. The fourth circuit 507 can switch the connection path between the second radiator 502 and the second signal source S2 to be connected or disconnected. The third circuit 506 and the fourth circuit 507 can switch according to the mode selection signal MD to determine whether the first radiator 501 receives the first signal and whether the second radiator 502 receives the second signal, thereby changing the radiation pattern of the antenna architecture 500.

[0060] In this embodiment, as Figure 5 As shown, based on the selection of the mode selection signal MD, the first circuit 504 connects the third radiator 503 to the first signal source S1; the second circuit 505 disconnects the third radiator 503 from the second signal source S2; the third circuit 506 disconnects the first radiator 501 from the first signal source S1; and the fourth circuit 507 connects the second radiator 502 to the second signal source S2. Through the selection of the mode selection signal MD, the first signal generated by the first signal source S1 is only provided to the third radiator 503. The third radiator 503 can form a first sub-antenna structure A1. The second signal generated by the second signal source S2 is only provided to the second radiator 502. The second radiator 502 can form a second sub-antenna structure A2. The antenna structure 500 of the present invention can be formed by changing the first sub-antenna structure A1 to use only the third radiator 503, thereby adjusting the radiation pattern of the antenna structure 500.

[0061] Please refer to Figure 6A and 6B . Figure 6A and 6B This is a schematic diagram illustrating the configuration of an antenna architecture on an electronic device in an embodiment of the present invention. Figure 6A and Figure 6B The antenna architecture 600 can be used for Figure 1 , Figures 3-5 Any of the antenna architectures in the embodiments. Figure 6A and 6B In this embodiment, a first radiator 601, a second radiator 602, and a third radiator 603 are disposed on the body portion 610 of the electronic device. The first radiator 601, the second radiator 602, and the third radiator 603 are respectively arranged along the X, Y, and Z axes, which are not identical. In this embodiment, the X, Y, and Z axes can be orthogonal to each other. The above arrangement is illustrative and is not intended to limit the invention.

[0062] exist Figure 6AIn this configuration, antenna architecture 600 can, based on a mode selection signal, form a first sub-antenna architecture A1 using only the first radiator 601, and a second sub-antenna architecture A2 using only the second radiator 602. For example... Figure 6A As shown, when the first sub-antenna architecture A1 transmits and receives signals, the main direction of the radiation pattern of the first sub-antenna architecture A1 can be direction D1. When the second sub-antenna architecture A2 transmits and receives signals, the main direction of the radiation pattern of the second sub-antenna architecture A2 can be direction D2. The first direction D1 and the second direction are not the same; in this embodiment, the first direction D1 and the second direction can, for example, be orthogonal to each other.

[0063] At Figure 6B In an embodiment of the first sub-antenna architecture A1', the antenna architecture 600 forms a first sub-antenna architecture A1' that shares the first radiator 601 and the third radiator 603, based on a mode selection signal. Figure 6B The first sub-antenna architecture A1' and Figure 6A Compared to the first sub-antenna architecture A1, the excitation energy of the first sub-antenna architecture A1 acts only on the first radiator 601, thus generating a radiation pattern with the main direction being direction D1. In contrast, a portion of the excitation energy of the first sub-antenna architecture A1' acts on the first radiator 601, and another portion acts on the third radiator 603. Because the first sub-antenna architecture A1' is jointly excited by the first radiator 601 and the third radiator 603 positioned along different axes, the main direction of the radiation pattern shifts from direction D1 to direction D3.

[0064] At Figure 6B In an embodiment of the second sub-antenna architecture A2', the antenna architecture 600 forms a second sub-antenna architecture A2' that shares the second radiator 602 and the third radiator 603, based on a mode selection signal. Similarly, it can be... Figure 6B The second sub-antenna architecture A2' and Figure 6A Compared to the second sub-antenna architecture A2, the second sub-antenna architecture A2' is excited by the second radiator 602 and the third radiator 603 set on different axes, causing the main direction of the radiation field pattern to shift from direction D2 to direction D4.

[0065] It is worth mentioning that, in this embodiment, the first to third radiators 601-603 can be arranged along the axes X, Y, and Z, respectively. The axes X, Y, and Z are not the same; in this embodiment, they can be mutually orthogonal. Therefore, taking the first sub-antenna architecture A1' and the second sub-antenna architecture A2' as examples, antenna architectures A1' and A2' can shift their radiation direction through the combined effect of the mutually orthogonal radiators to achieve optimal field pattern adjustment. In this embodiment, taking the first sub-antenna architecture A1' as an example, the direction of the transmitted signal of the first sub-antenna architecture A1' can be adjusted by adjusting the excitation energy intensity of at least one of the two mutually orthogonal radiators in the first sub-antenna architecture A1'.

[0066] Please refer to Figure 7A and 7B . Figure 7A and Figure 7B This is a schematic diagram illustrating an implementation method for increasing antenna isolation in the antenna architecture of the present invention. Figure 7A The antenna architecture 700a includes a first signal source S1, a second signal source S2, a first radiator 701a, a second radiator 702a, a third radiator 703a, a first circuit 704a, a second circuit 705a, and impedance matching circuits 706a and 707a. Figure 7B The antenna architecture 700b includes a first signal source S1, a second signal source S2, a first radiator 701b, a second radiator 702b, a third radiator 703b, a first circuit 704b, a second circuit 705b, and impedance matching circuits 706b and 707b.

[0067] Figure 7A Implementation examples and Figure 3The difference in the embodiment is that, in antenna architecture 700a, one end of the third radiator 703a can be coupled to a reference ground terminal GND. The endpoint of the third radiator 703a coupled to the reference ground terminal GND can have the same or different distances from the endpoints coupled to the first circuit 704a and the second circuit 705a, respectively. Depending on the selection of the mode selection signal MD, the first circuit 704a can disconnect the connection between the third radiator 703a and the first radiator 701a; the second circuit 705a can disconnect the connection between the third radiator 703a and the second radiator 702a. Therefore, in antenna architecture 700a, the first radiator 701a receives the first signal to form a first sub-antenna architecture A1; and the second radiator 702a receives the second signal to form a second sub-antenna architecture A2. The third radiator 703a, by being disposed between the first radiator 701a and the second radiator 702a and by being coupled to the reference ground terminal GND, increases the isolation between the first sub-antenna architecture A1 and the second sub-antenna architecture A2. In some embodiments of the present invention, the third radiator 703a may also be optionally not coupled to the reference ground terminal GND, and the isolation between the first sub-antenna architecture A1 and the second sub-antenna architecture A2 can still be increased by utilizing the structure of the third radiator 703a itself.

[0068] Similarly, Figure 7B Implementation examples and Figure 4 The difference in the embodiment is that, in antenna architecture 700b, one end of the third radiator 703b can be coupled to the reference ground terminal GND. The endpoint of the third radiator 703b coupled to the reference ground terminal GND can have the same or different distances from the endpoints coupled to the first circuit 704b and the second circuit 705b, respectively. Depending on the selection of the mode selection signal MD, the first circuit 704b can disconnect the connection between the third radiator 703b and the first signal source S1; the second circuit 705b can disconnect the connection between the third radiator 703b and the second signal source S2. Therefore, in antenna architecture 700b, the first radiator 701b receives the first signal to form the first sub-antenna architecture A1; the second radiator 702b receives the second signal to form the second sub-antenna architecture A2. The third radiator 703b, by being positioned between the first radiator 701b and the second radiator 702b, and through its coupling to the reference ground terminal GND, increases the isolation between the first sub-antenna architecture A1 and the second sub-antenna architecture A2. In some embodiments of the present invention, the third radiator 703b may also be uncoupled to the reference ground terminal GND, and the structure of the third radiator 703b itself can also increase the isolation between the first sub-antenna architecture A1 and the second sub-antenna architecture A2.

[0069] It is worth mentioning that, in some embodiments, Figure 7A and 7BThe third radiators 703a and 703b can also be formed by an extension structure of the main ground plane on the electronic device provided by the antenna architectures 700a and 700b, so as to increase the isolation between the first sub-antenna architecture A1 and the second sub-antenna architecture A2.

[0070] In many embodiments of the present invention, the first to third radiators can be disposed on an electronic device in various ways. In some embodiments of the present invention, the first to third radiators can be part of the metal casing of the electronic device. Please refer to... Figure 8A and Figure 8B . Figure 8A and Figure 8B This is a schematic diagram illustrating an embodiment of certain antenna configurations of the present invention. Figure 8A In the present invention, the metal casing 800a is rectangular in shape, having a corner portion F3a, a first extension F1a adjacent to the first side of the corner portion F3a, and a second extension F2a adjacent to the second side of the corner portion F3a. In one embodiment of the present invention, the corner portion F3a can be configured as the third radiator of the present invention, the first extension F1a can be configured as the first radiator of the present invention, and the second extension F2a can be configured as the second radiator of the present invention. In other embodiments of the present invention, the arrangement relationship between the corner portion F3a, the first extension F1a, and the second extension F2a and the first to third radiators of the present invention can be any other arbitrary arrangement and combination. Furthermore, the metal casing of the present invention is not limited to a rectangular shape but can be any polygonal shape. Figure 8B For example, the metal casing 800b is triangular in shape and has a corner portion F3b, a first extension portion F1b adjacent to the first side of the corner portion F3b, and a second extension portion F2b adjacent to the second side of the corner portion F3b.

[0071] In summary, the antenna architecture of the present invention can be configured in an electronic device, and the radiation pattern of the antenna architecture can be adjusted and / or the isolation of the antenna architecture can be increased according to the selection of the mode selection signal to achieve the best communication quality.
