Description

Technical Field

[0001] The present invention relates to a power distribution component and a transceiver device including the power distribution component, and more particularly to a power distribution component and a wireless transceiver device including the power distribution component. Background Technology

[0002] Currently, USB wireless transceivers (USB dongles) with audio jacks on the market typically position their internal antennas away from the audio jack's location, or they may have two antennas mounted on the USB wireless transceiver and switch their operation on a switch, in order to prevent the antennas from being blocked by the audio jack and affecting their radiation performance.

[0003] However, antennas positioned to avoid the audio jack are often biased towards one side of the USB transceiver, causing the antenna pattern to be biased to that side and creating dead zones in signal reception. Using two sets of antennas on the USB transceiver with a switch to operate them requires significant manufacturing costs. Therefore, developing a USB transceiver with an audio jack that offers good antenna radiation performance without increasing manufacturing costs is an important research direction in this field. Summary of the Invention

[0004] The present invention relates to a power distribution component and a wireless transceiver device, which respectively have good power distribution performance and good antenna radiation performance.

[0005] According to an embodiment of the present invention, a power distribution component includes a wavelength converter, a connection portion, a first power distribution portion, and a second power distribution portion. The wavelength converter has an input terminal and a connection terminal. The connection portion includes a first connection terminal and a second connection terminal, and the first connection terminal is connected to the connection terminal of the wavelength converter. The first power distribution portion includes a first output port and a first end, and the first end is connected to the second connection terminal of the connection portion. The second power distribution portion includes a second output port and a second end, and the second end is connected to the second connection terminal of the connection portion. The first power distribution portion and the second power distribution portion are symmetrically and mirror-imagely disposed on opposite sides of the connection portion with the connection portion as a mirror axis.

[0006] According to an embodiment of the present invention, the wireless transceiver includes a circuit board, an audio jack, a chip, a power distribution component, and two antenna assemblies. The audio jack is disposed on the edge of the circuit board, and the chip is disposed on the circuit board. The power distribution component is disposed on the circuit board and electrically connected to the chip. The two antenna assemblies are disposed on the circuit board and electrically connected to the power distribution component, and are symmetrically and mirrorively disposed on opposite sides of the audio jack.

[0007] In an embodiment of the present invention, the first output port of the first power distribution unit and the second output port of the second power distribution unit are adapted to be connected to two antenna components respectively, the two antenna components are adapted to resonate a frequency band, and the wavelength converter includes a microstrip line with a length of 1 / 4 wavelength of the frequency band.

[0008] In an embodiment of the present invention, the width of the connection portion is greater than the width of the microstrip line, and the width of the microstrip line is greater than the width of either the first power distribution portion or the second power distribution portion.

[0009] In an embodiment of the invention, the microstrip line includes a plurality of first segments that are sequentially bent and connected, wherein the distance between any two adjacent and parallel segments is between 0.1 mm and 0.3 mm.

[0010] In an embodiment of the invention, either the first power distribution section or the second power distribution section includes a plurality of second segments that are sequentially bent and connected, wherein the distance between any two adjacent and parallel second segments is between 0.1 mm and 0.6 mm.

[0011] In an embodiment of the invention, the distance between the second segment closest to the connecting portion and parallel to the connecting portion and the connecting portion is between 0.1 mm and 0.3 mm.

[0012] In an embodiment of the invention, the length of the power divider along the extension direction of the connection is between 1.8 mm and 2 mm.

[0013] In an embodiment of the invention, the power distribution component has a length between 6 mm and 10 mm and a width between 4 mm and 6 mm.

[0014] In an embodiment of the present invention, the first output port of the first power distribution section and the second output port of the second power distribution section are adapted to be connected to two antenna components respectively, the two antenna components are adapted to resonate a frequency band, and the length of either the first power distribution section or the second power distribution section is 1 / 4 of the wavelength of the frequency band.

[0015] Based on the above, in the power distribution assembly of the present invention, because the first power distribution section and the second power distribution section are symmetrically and mirror-imagely disposed on opposite sides of the connecting section with the connecting section as the mirror axis, the power distribution assembly can effectively divide the output power into two and transmit it to the two antenna assemblies electrically connected to the power distribution assembly. The two antenna assemblies can then operate independently and simultaneously due to the division of the output power into two.

[0016] Furthermore, in the wireless transceiver of the present invention, the two antenna components connected to the power distribution component are symmetrically and mirror-orientedly arranged on opposite sides of the audio jack. This allows the two antenna components to avoid obstruction by the audio jack and achieve good radiation performance, and the two antenna components combine the antenna patterns located on opposite sides of the audio jack to achieve excellent omnidirectional performance. Moreover, compared to prior art wireless transceivers that include a switch, the wireless transceiver of the present invention, by arranging the two antenna components on opposite sides of the audio jack, eliminates the need for a switch to switch the antenna operating state, thus achieving good antenna radiation performance and saving the cost of configuring a switch on the wireless transceiver.

[0050] Figure 1 This is a top view of a wireless transceiver device according to an embodiment of the present invention. Please refer to... Figure 1 The wireless transceiver 10 of this embodiment includes a circuit board 11, an audio jack 12, a chip 13, a power distribution component 100, and two antenna assemblies 14A and 14B. The audio jack 12 is disposed on the edge of the circuit board 11, while the chip 13 is disposed on the circuit board 11. The power distribution component 100 is disposed on the circuit board 11 and electrically connected to the chip 13. The two antenna assemblies 14A and 14B are disposed on the circuit board 11 and electrically connected to the power distribution component 100. Furthermore, the two antenna assemblies 14A and 14B are symmetrically and mirror-reflectively disposed on opposite sides of the audio jack 12.

[0051] Figure 2 yes Figure 1A partially enlarged top view of the wireless transceiver device. Figure 3 yes Figure 1 A top-view diagram of the power distribution components of a wireless transceiver. Please refer to... Figures 1 to 3 The power distribution component 100 in this embodiment includes a wavelength converter 110, a connection portion 120, a first power distribution portion 130, and a second power distribution portion 140. The wavelength converter 110 is connected to the chip 13 ( Figure 1 ), and wavelength converter 110 such Figure 3 The diagram shows an input terminal 111 and a connection terminal 112. The connection portion 120 includes a first connection terminal 121 and a second connection terminal 122, and the first connection terminal 121 is connected to the connection terminal 112 of the wavelength converter 110.

[0052] In this embodiment, the first power distribution unit 130 includes a first output port 131 and a first end 132, and the first end 132 is connected to the second connection end 122 of the connecting unit 120. The second power distribution unit 140 includes a second output port 141 and a second end 142, and the second end 142 is connected to the second connection end 122 of the connecting unit 120. The first power distribution unit 130 and the second power distribution unit 140 are as follows: Figure 2 and Figure 3 As shown, the antennas are symmetrically and mirror-imagely arranged on opposite sides of the connecting portion 120, with the connecting portion 120 as the mirror axis. The first power distribution portion 130 and the second power distribution portion 140 are connected to the two antenna assemblies 14A and 14B. Figure 1 , 2 ).

[0053] Furthermore, in this embodiment, the first output port 131 of the first power distribution unit 130 and the second output port 141 of the second power distribution unit 140 are adapted to be connected to the two antenna assemblies 14A and 14B, respectively. The first power distribution unit 130 is connected via its first output port 131 to the audio jack 12 ( Figure 1 The antenna assembly 14A is located on one side of the second power distribution unit 140, which is connected via a second output port 141 to the audio jack 12. Figure 1 Antenna assembly 14B on the other side.

[0054] In this way, because the first power distribution section 130 and the second power distribution section 140 are symmetrically and mirrorally arranged on opposite sides of the connecting section 120 with the connecting section 120 as the mirror axis, the power distribution component 100 in this embodiment can effectively divide the output power into two and transmit it to the two antenna components 14A and 14B electrically connected to the power distribution component 100. The two antenna components 14A and 14B can operate independently and simultaneously because the output power is divided into two.

[0055] Furthermore, in this embodiment, the first power distribution unit 130 and the second power distribution unit 140 respectively transmit the evenly distributed power to the antenna assemblies 14A and 14B located on both sides of the audio jack 12 through the first output port 131 and the second output port 141. In this way, the antenna assemblies 14A and 14B can avoid the obstruction of the audio jack 12 and have good radiation performance. Moreover, the antenna assemblies 14A and 14B can combine the antenna patterns located on opposite sides of the audio jack 12 to achieve excellent omnidirectional performance.

[0056] Furthermore, compared to prior art wireless transceivers that include switches, the wireless transceiver device 10 of this embodiment has good antenna radiation performance because it sets the two antenna components 14A and 14B on opposite sides of the audio jack 12, without the need to configure a switch for switching the antenna operating state, thus saving the cost of configuring a switch on the wireless transceiver device 10.

[0057] In this embodiment, the antenna components 14A and 14B of the wireless transceiver 10 are adapted to couple out a frequency band, and the value of the frequency band is 2.4 GHz. The wavelength converter 110 includes a microstrip line 113 with a length of 1 / 4 wavelength of the frequency band, and the length of either the first power distribution section 130 or the second power distribution section 140 is 1 / 4 wavelength of the frequency band. It is worth mentioning that the wireless transceiver 10 of this embodiment can adjust the lengths of the microstrip line 113, the first power distribution section 130, and the second power distribution section 140 so that both antenna components 14A and 14B can resonate out an ideal frequency band and achieve the effect of customized design. The present invention does not limit the value of the frequency band resonated by the wireless transceiver 10 or the lengths of the microstrip line 113, the first power distribution section 130, and the second power distribution section 140.

[0058] Furthermore, in this embodiment, the width of the connection portion 120 is greater than the width of the microstrip line 113, and the width of the microstrip line 113 is greater than the width of either the first power distribution portion 130 or the second power distribution portion 140. The impedance of the connection portion 120 is 25 ohms, the impedance of the microstrip line 113 is 35 ohms, and the impedances of both the first power distribution portion 130 and the second power distribution portion 140 are 50 ohms. It is worth noting that in this embodiment, the widths of the connection portion 120, the microstrip line 113, the first power distribution portion 130, and the second power distribution portion 140 can be adjusted to achieve ideal impedance matching, so that the first output port 131 of the first power distribution portion 130 and the second output port 141 of the second power distribution portion 140 can both obtain ideal output impedance and achieve customization. This invention does not limit the widths of the connection portion 120, the microstrip line 113, the first power distribution portion 130, and the second power distribution portion 140.

[0059] Figure 4 yes Figure 3 A partially enlarged top view of the power distribution components. Please refer to... Figure 1 , Figure 3 and Figure 4 The length L1 of the power distribution component 100 in this embodiment is ( Figure 3 The width is between 6 mm and 10 mm, and the width W1 ( Figure 3 The microstrip line 113 of the wavelength converter 110 is between 4 mm and 6 mm. Figure 4 The diagram shows a plurality of first segments 114 connected in a sequentially bent manner. In each of the first segments 114, any two adjacent and parallel segments have distances D1, D2, and D3, all of which are between 0.1 mm and 0.3 mm. This design allows the wavelength converter 110 to effectively reduce the coupling effect between the plurality of first segments 114 due to the design of the distances D1, D2, and D3 between the first segments 114. The antenna assembly 14A of the wireless transceiver 10 (… Figure 1 ) and antenna assembly 14B ( Figure 1 Therefore, it performs well in terms of reflux loss and isolation.

[0060] In this embodiment, when the distances D1 and D2 are between 0.1 mm and 0.3 mm, and the distance D3 is between 0.2 mm and 0.3 mm, the antenna components 14A and 14B of the wireless transceiver 10 can achieve ideal isolation and return loss of less than -20 dB, thus exhibiting good radiation performance.

[0061] Figure 5 yes Figure 3 A partially enlarged top view of the power distribution components. Please refer to... Figure 1 , Figure 3 and Figure 5 In this embodiment, either the first power distribution section 130 or the second power distribution section 140 includes a plurality of second segments 150 that are sequentially bent and connected. In the second segments 150, the distances D4, D5, D6, and D7 between any two adjacent and parallel segments are all between 0.1 mm and 0.6 mm. Furthermore, the distance D8 between the second segment 150 closest to and parallel to the connecting portion 120 and the connecting portion 120 is between 0.1 mm and 0.3 mm.

[0062] Therefore, the first power distribution unit 130 and the second power distribution unit 140 of this embodiment can effectively reduce the coupling effect between the multiple second segments 150 due to the design of distances D4, D5, D6, D7 and D8, and the antenna assembly 14A of the wireless transceiver device 10 ( Figure 1) and antenna assembly 14B ( Figure 1 Therefore, it performs well in terms of reflux loss and isolation.

[0063] In this embodiment, when distances D4 and D5 are between 0.1 mm and 0.3 mm, distances D6 and D8 are between 0.13 mm and 0.33 mm, and distance D7 is between 0.35 mm and 0.55 mm, the antenna assemblies 14A and 14B of the wireless transceiver 10 can achieve ideal isolation and return current loss of less than -20 dB, thus exhibiting good radiation performance.

[0064] Furthermore, in this embodiment, the length L2 of the first power distribution section 130 and the second power distribution section 140 along the extension direction of the connecting section 120 is between 1.8 mm and 2 mm. The longer the length L2, the lower the frequency band resonated by the antenna components 14A and 14B. The wireless transceiver 10 can change the frequency band values ​​resonated by the antenna components 14A and 14B by adjusting the length L2, achieving a customized design effect.

[0065] Furthermore, such as Figure 5 As shown, in this embodiment, a resistor R is provided between the first power distribution unit 130 and the second power distribution unit 140 in their respective second sections 150. Thereby, the second sections 150 located on both sides of the resistor R can reduce the coupling effect between them due to the high resistance value of the resistor R, thereby preventing signal interference between the first power distribution unit 130 and the second power distribution unit 140. Antenna assemblies 14A located on both sides of the audio jack 12 ( Figure 1 ) and antenna assembly 14B ( Figure 1 The first power distribution unit 130 and the second power distribution unit 140 can also operate independently because they do not interfere with each other. The resistance value of the resistor R in this embodiment is 100 ohms, but the present invention does not limit the resistance value of the resistor R.

[0066] Figure 6 yes Figure 1 Antenna pattern distribution diagram of the wireless transceiver device. Please refer to... Figure 1 and Figure 6 In this embodiment, when the antenna assemblies 14A and 14B located on both sides of the audio jack 12 operate simultaneously, the antenna field patterns excited by the antenna assemblies 14A and 14B on both sides of the audio jack 12 respectively can combine with each other to form a pattern such as... Figure 6 The antenna pattern shown achieves excellent omnidirectional performance.

[0067] In summary, in the power distribution assembly of the present invention, because the first power distribution section and the second power distribution section are symmetrically and mirror-imagely disposed on opposite sides of the connecting section with the connecting section as the mirror axis, the power distribution assembly can effectively divide the output power into two and transmit it to the two antenna assemblies electrically connected to the power distribution assembly. The two antenna assemblies can then operate independently and simultaneously due to the division of the output power into two.

[0068] In the wireless transceiver device of the present invention, two antenna components connected to the power distribution component are symmetrically and mirror-orientedly arranged on opposite sides of the audio jack. This allows the two antenna components to avoid obstruction by the audio jack and achieve good radiation performance. Furthermore, the two antenna components combine the antenna patterns located on opposite sides of the audio jack to achieve excellent omnidirectional performance. Moreover, compared to prior art wireless transceivers that include a switch, the wireless transceiver device of the present invention, by arranging the two antenna components on opposite sides of the audio jack, eliminates the need for a switch to switch the antenna operating state, thus achieving good antenna radiation performance and saving the cost of configuring a switch on the wireless transceiver device.

[0069] Furthermore, in one embodiment of the wireless transceiver device, the lengths of the microstrip line, the first power distribution section, and the second power distribution section can be adjusted to allow the two antenna components to resonate at an ideal frequency band, achieving a customized design effect. In another embodiment, the widths of the connector, microstrip line, first power distribution section, and second power distribution section can be adjusted to achieve ideal impedance matching, ensuring that both the first output port of the first power distribution section and the second output port of the second power distribution section achieve ideal output impedance, thus achieving a customized design effect. Additionally, in one embodiment, the wavelength converter effectively reduces the coupling effect between multiple first segments due to the distance design between each first segment, and the first and second power distribution sections also effectively reduce the coupling effect between multiple second segments due to the distance design between each second segment. Therefore, the two antenna components of the wireless transceiver device exhibit excellent performance in terms of return current loss and isolation.

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
