[0062] Figure 1 This is a schematic diagram of a signal transceiver according to an embodiment of the present invention. Figure 2 of Figure 1 Another perspective view of the signal transceiver with its housing removed. Figure 3A of Figure 1 A cross-sectional view of a signal transceiver. This is to clearly illustrate the internal structure of the signal transceiver. Figure 1 The casing is shown in dashed lines. Furthermore, Figure 3A The package 150 is schematically shown in an irregular dot pattern.

[0063] Please see Figure 1 to Figure 3A The transceiver 100 of this embodiment is suitable for interface with the USB Type-C interface of electronic devices such as computers, laptops, or mobile phones, but the electronic devices to which the transceiver 100 is applicable are not limited thereto. Electronic devices can wirelessly transmit data with other devices through the transceiver 100 without the need for a physical cable to connect to the USB Type-C interface, making it quite convenient and flexible to use.

[0064] Specifically, the signal transceiver 100 includes a circuit board 110, an electrical connection portion 120, an antenna radiator 130, and a housing 140. The housing 140 has an accommodating space A. Figure 3A), the circuit board 110 and the antenna radiator 130 are disposed in the accommodation space A. The circuit board 110 is disposed close to the bottom 142 of the housing 140 (see FIG. 1) to reduce the volume of the signal transceiver 100. The circuit board 110 has opposite first and second faces 112 and 114. Figure 3A

[0065] The electrical connection portion 120 is disposed on the second face 114 of the circuit board 110 and has an electrical connection direction E. At least a portion of the electrical connection portion 120 is exposed outside the housing 140 and can be connected to a USB Type-C interface of an electronic device such as a computer, a notebook computer, or a mobile phone along the electrical connection direction E.

[0066] The signal transceiver 100 can receive and transmit radio frequency signals through the antenna radiator 130. In detail, the antenna radiator 130 includes a radiating main body 132 and at least one connecting segment 136 connected to each other. The radiating main body 132 is projected on the plane of the circuit board 110 to coincide with the first face 112 of the circuit board 110. In the present embodiment, the at least one connecting segment 136 includes three connecting segments 1361, 1362, and 1363. The radiating main body 132 is parallel to the circuit board 110 and is connected to the first face 112 of the circuit board 110 through the connecting segments 1361, 1362, and 1363.

[0067] More specifically, the circuit board 110 includes at least one electrical connection portion 116, the number of the electrical connection portions 116 corresponding to the number of the connecting segments 136 (the electrical connection portions 116 in the present embodiment are shown as three). The connecting segments 1361, 1362, and 1363 are respectively fixed to the corresponding electrical connection portions 116 to connect the radiating main body 132 to the circuit board 110. The electrical connection portions 116 can be in the form of openings for the connecting segments 1361, 1362, and 1363 to be fixed in an insertion manner. Alternatively, the electrical connection portions 116 can be metal electrically connected to the circuit board 110 for the connecting segments 1361, 1362, and 1363 to be fixed in a welding manner.

[0068] In the present embodiment, the connecting segments 1361, 1362, and 1363 respectively include a feed-in end F1, a grounding end F2, and a positioning end F3. The feed-in end F1 of the connecting segment 1361 can feed signals into the circuit board 110 or the radiating main body 132. The grounding end F2 of the connecting segment 1362 is used to achieve a grounding effect. The positioning end F3 of the connecting segment 1363 provides a positioning function and makes the radiating main body 132 stably connected to the circuit board 110.

[0069] In addition, the connecting segments 1361, 1362, and 1363 in the present embodiment are respectively disposed on the side and the corner of the circuit board 110, but the positions of the connecting segments 1361, 1362, and 1363 on the circuit board 110 are not limited thereto.

[0070] ​In the embodiment, the radiation body 132 has two first long sides and two first short sides, and the circuit board 110 has two second long sides and two second short sides. The length of the first long side of the radiation body 132 is greater than or equal to the length of the first short side, and the length of the second long side of the circuit board 110 is greater than or equal to the length of the second short side.

[0071] The first long side direction L1 and the first short side direction S1 of the radiation body 132 correspond to the second long side direction L2 and the second short side direction S2 of the circuit board 110 respectively. The first long side direction L1 and the first short side direction S1 are parallel to the long side and the short side of the radiation body 132 respectively, and the second long side direction L2 and the second short side direction S2 are parallel to the long side and the short side of the circuit board 110 respectively. In the embodiment, the first long side direction L1 is parallel to the second long side direction L2 of the circuit board 110, and the first short side direction S1 is parallel to the second short side direction S2. In addition, the first long side of the radiation body 132 extends along the second long side direction L2 but does not exceed the length of the second long side of the circuit board 110, and the first short side of the radiation body 132 extends along the second short side direction S2 but does not exceed the length of the second short side of the circuit board 110.

[0072] On the other hand, the antenna radiation body 130 of the embodiment is integrally formed. The connecting segments 1361, 1362, 1363 are bent from the radiation body 132 and extend along the electrical connection direction E towards the circuit board 110, and the gap G between the radiation body 132 and the circuit board 110 is between 1 millimeter and 5 millimeters. The electrical connection direction E is different from the first long side direction L1 and the first short side direction S1. In an embodiment, the electrical connection direction E is perpendicular to the first long side direction L1 and the first short side direction S1, that is, the connecting segments 1361, 1362, 1363 are perpendicular to the circuit board 110.

[0073] Through the above design of the bent antenna, the length of the signal transceiver 100 in the electrical connection direction E can be reduced, thereby reducing the space occupied by the signal transceiver 100 and facilitating device miniaturization.

[0074] In the embodiment, the radiation body 132 is a block-shaped printed radiation body. The printed radiation body has a second circuit board and a printed radiation layer. The printed radiation layer is metal and can be formed on the surface of the second circuit board by etching, chemical deposition, electroplating, screen printing, intaglio printing, silver paste inkjet, or stamping, etc.

[0075] The antenna radiator 130 can generate wireless signals in the ISM band, which has a frequency range of 1710-7125 MHz, particularly in the short-range low-power band, such as 2400-2500 MHz and 5725-5875 MHz. In one embodiment, the antenna radiator 130 generates a resonance frequency of about 2.4 GHz (with a frequency range of 2400-2480 MHz), and the path length of the antenna radiator 130 is 1 / 4 of the wavelength of the resonance frequency. In another embodiment, the antenna radiator 130 generates a resonance frequency of about 5 GHz.

[0076] In addition, as shown in Figure 3A , the signal transceiver 100 of the present embodiment further includes an encapsulant 150. The encapsulant 150 can be made of a polymer material, such as epoxy, polyurethane, polyamide, or silicone, and is disposed in the receiving space A of the housing 140. In some embodiments, the encapsulant 150 covers all surfaces of the circuit board 110, including the first face 112 and the second face 114. In other embodiments, the encapsulant 150 covers at least the circuit board 110 and the antenna radiator 130. Furthermore, the encapsulant 150 can be formed in the housing 140 by a potting method, or can be formed by a potting or injection molding method and then combined with the housing 140. In some embodiments, the encapsulant 150 can be hardened by baking, thereby stably disposing the antenna radiator 130 in the housing 140.

[0077] Figure 3B is a cross-sectional view of a signal transceiver according to another embodiment of the present application. Figure 3B The main difference between the embodiment shown in Figure 3A and the embodiment shown in Figure 3B is that the amount of potting of the encapsulant 150' in the signal transceiver 100' is different.

[0078] Specifically, the encapsulant 150' of the present embodiment covers the circuit board 110 and the antenna radiator 130, and there is a gap G1 between the encapsulant 150' and the inner top wall 146 of the housing 140. In other words, the encapsulant 150' does not completely fill the receiving space A, so that the weight and production cost of the signal transceiver 100' can be further reduced while stably disposing the antenna radiator 130.

[0079] Figure 4 is a schematic view of a signal transceiver according to another embodiment of the present application. Figure 4 The main difference between the embodiment shown in Figure 1 to Figure 3A and the embodiment shown in Figure 4 is that the number of connection segments 136a in the signal transceiver 100a is two (shown as connection segments 1361a, 1362a).
