[0003] In related technologies, some walkie-talkie antennas transmit signals by winding the antenna body into a specific shape. The antenna body uses a rubber ring, within which a metal wire is placed. This metal wire transmits the signal and is electrically connected to the walkie-talkie. However, in this design, the rubber ring easily causes some signal absorption or attenuation, resulting in poor signal stability, low antenna gain, and a narrow antenna bandwidth.

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0025] This utility model embodiment provides a LOOP walkie-talkie antenna, such as Figure 1 As shown, the LOOP walkie-talkie antenna includes an antenna mount 110, a connector 120, an exposed metal ring 130, and a metal branch line 140. The connector 120 is used for electrical connection with an external walkie-talkie and is fixed to the bottom of the antenna mount 110. The metal ring 130 is electrically connected to the connector 120 and is fixed to the top of the antenna mount 110. The metal branch line 140 is located in the inner ring of the metal ring 130, and its two ends are electrically connected to different positions of the metal ring 130.

[0026] The LOOP walkie-talkie antenna in this embodiment uses an antenna mount 110 with a connector 120 fixedly mounted at the bottom. The LOOP walkie-talkie antenna can be electrically connected to an external walkie-talkie via the connector 120. An exposed metal ring 130 and a metal branch line 140 are fixedly mounted on the top of the antenna mount 110. The metal ring 130 directly serves as one loop of the LOOP walkie-talkie antenna. Using an exposed metal ring 130 can reduce losses, improve anti-interference capabilities, and enhance signal stability and antenna gain. In this application, the metal branch line 140 is also located within the inner ring of the metal ring 130, and its two ends are electrically connected to different positions of the metal ring 130. The metal branch line 140 serves as another loop of the LOOP walkie-talkie antenna, forming a dual-loop antenna. This helps to broaden the bandwidth of the LOOP walkie-talkie antenna and improve its ability to receive signals with different polarizations.

[0027] Among them, the metal branch 140 serves as a loop and can be responsible for signal transmission within a specific frequency range. The outer metal ring 130 is a closed loop and serves as another loop, which can process signals of different frequencies or polarizations. Therefore, the dual-loop antenna structure design of this application can broaden the bandwidth and improve the LOOP walkie-talkie antenna's ability to receive signals of different polarizations.

[0028] The metal ring 130 and the connector 120 can be electrically connected by a wire or by a conductive post.

[0029] The LOOP walkie-talkie antenna of this application has dual-band functionality, enabling communication on two different frequency bands, including the Ultra High Frequency (UHF) and Very High Frequency (VHF) bands, and can be used in outdoor adventure, camping and other application scenarios.

[0030] In an optional embodiment of this application, the metal ring 130 and the metal branch 140 are made of the same material, and the material is one of copper, aluminum, or titanium.

[0031] Preferably, both the metal ring 130 and the metal branch line 140 are made of copper. Copper has low resistance and good conductivity. As the material for the metal ring 130 and the metal branch line 140 to realize signal transmission, it can reduce energy loss during signal transmission, improve the efficiency and performance of the LOOP walkie-talkie antenna, and has good corrosion resistance, which can resist oxidation and corrosion under most environmental conditions, making the LOOP walkie-talkie antenna more durable and stable, and able to maintain good performance for a long time. Copper is also easy to process and form, and it is easy to manufacture copper rings and copper branch lines, making the whole device lighter.

[0032] refer to Figure 1 and Figure 2 In an optional embodiment of this application, the connector 120 is an SMA female connector 121, which is electrically connected to the metal ring 130 and the external walkie-talkie respectively.

[0033] The SMA connector 121 is compatible with the antenna interfaces of different walkie-talkie models, providing excellent connection performance and wide compatibility. Users can rotate the looper on the walkie-talkie antenna and connect the SMA connector 121 to the walkie-talkie's antenna interface to achieve an electrical connection, making installation very convenient.

[0034] In other embodiments, connector 120 may also use an SMA connector male, which can be adapted by those skilled in the art.

[0035] Further, refer to Figures 1 to 3In an optional embodiment of this application, the LOOP walkie-talkie antenna further includes a stacked elastic ring 150 and a gasket 160. The gasket 160 is provided with a through hole 151. The SMA connector 121 is provided with the elastic ring 150 and the through hole 151. After the SMA connector 121 is electrically connected to the external walkie-talkie, the elastic ring 150 and the gasket 160 are sandwiched between the antenna mount 110 and the external walkie-talkie.

[0036] The design of the elastic ring 150 can provide a certain degree of damping and shock absorption. The elastic ring 150 and the gasket 160 are stacked and sandwiched between the antenna mount 110 and the external walkie-talkie. This can increase the friction between the SMA connector 121 and the external walkie-talkie, prevent the connection from becoming loose due to vibration or accidental collision, and thus ensure the stability of signal transmission.

[0037] The elastic band 150 can be made of elastic materials such as rubber and silicone, and has a certain damping and cushioning effect.

[0038] refer to Figure 1 and Figure 2 In an optional embodiment of this application, an anti-slip part 111 is provided on the outer surface of the antenna holder 110 near the connector 120.

[0039] When the user rotates the LOOP walkie-talkie antenna to electrically connect the connector 120 to the walkie-talkie, the user can hold the anti-slip part 111. The anti-slip part 111 can increase the friction between the outer surface of the antenna mount 110 and the user's grip surface, making it easier to assemble the LOOP walkie-talkie antenna onto the walkie-talkie.

[0040] In practice, patterns can be set on the outer surface of the antenna mount 110 to form an anti-slip part 111, such as wavy patterns, raised dot arrays, grid patterns, cross lines, etc. Designers can set them as needed. These can increase the friction of the outer surface of the antenna mount 110, provide a better anti-slip effect, and facilitate the assembly between the LOOP walkie-talkie antenna and the walkie-talkie.

[0041] refer to Figure 1 and Figure 2 In an optional embodiment of this application, an insulating gripping part 131 is provided on the metal ring 130 on the opposite side of the antenna mount 110.

[0042] By providing an insulated grip part 131, a grip area that is isolated from the metal ring 130 is provided. Users can grip the insulated grip part 131 to move the LOOP walkie-talkie antenna, improving operational convenience. Furthermore, since the insulated grip part 131 is only provided on the opposite side of the antenna mount 110, it will not affect the signal reception of the metal ring 130 and the metal branch line 140.

[0043] The insulating grip part 131 can be made of insulating materials such as ABS plastic, polyethylene, and epoxy resin.

[0044] In an optional embodiment of this application, an optical emission circuit 170 is provided inside the antenna mount 110. The optical emission circuit 170 is connected in series with the metal ring 130 so as to emit light when the metal ring 130 receives a signal.

[0045] By setting up the light-emitting circuit 170, it can serve as a signal reception indicator, informing the user of the status of the LOOP walkie-talkie antenna's signal reception, allowing the user to know whether the LOOP walkie-talkie antenna is working properly, and improving the user experience.

[0046] Further, refer to Figure 1 and Figure 4 The antenna mount 110 has a light-emitting hole 112. The light-emitting circuit 170 includes a detector circuit unit 171 and a light-emitting diode D1. The detector circuit unit 171 is connected to the positive and negative terminals of the light-emitting diode D1 and is connected to the metal ring 130. The light-emitting diode D1 extends out of the light-emitting hole 112.

[0047] By setting up the detection circuit unit 171, the detection circuit unit 171 can drive the light-emitting diode D1 to light up after the metal ring 130 receives the signal, indicating the signal status of the LOOP walkie-talkie antenna. The light-emitting diode D1 is partially extended out of the light-emitting hole 112, which can expand the light-emitting range and make it easier for the user to observe the light-emitting status of the light-emitting diode D1.

[0048] Specifically, refer to Figure 4 The detection circuit unit 171 includes an inductor L1 and a detector diode D2. One end of the inductor L1 is connected to the metal ring 130 and the positive terminal of the detector diode D2, and the other end is connected to the negative terminal of the light-emitting diode D1. The negative terminal of the detector diode D2 is connected to the positive terminal of the light-emitting diode D1.

[0049] When the metal ring 130 receives a signal, the inductor L1 induces electromagnetic waves to generate a high-frequency current. This high-frequency current is rectified into DC by the detector diode D2, causing the LED D1 connected in series in this circuit to operate, indicating signal reception. The circuit structure of this LED circuit 170 is simple, which is beneficial for the miniaturization of the LOOP walkie-talkie antenna.

[0050] This application also provides a walkie-talkie. The walkie-talkie includes a walkie-talkie body and a LOOP walkie-talkie antenna as described above. The walkie-talkie body is provided with an antenna interface, which is electrically connected to the connector 120 of the LOOP walkie-talkie antenna.

[0051] In this embodiment of the walkie-talkie, the LOOP walkie-talkie antenna is mounted on an antenna base 110. A connector 120 is fixedly mounted at the bottom of the antenna base 110. The LOOP walkie-talkie antenna can be electrically connected to the walkie-talkie body through the connector 120. An exposed metal ring 130 and a metal branch line 140 are fixedly mounted on the top of the antenna base 110. The metal ring 130 directly serves as one loop of the LOOP walkie-talkie antenna. Using an exposed metal ring 130 can reduce losses, improve anti-interference ability, improve signal stability and antenna gain. In this application, the metal branch line 140 is also set in the inner ring of the metal ring 130, and its two ends are electrically connected to different positions of the metal ring 130. The metal branch line 140 serves as another loop of the LOOP walkie-talkie antenna, forming a dual-loop antenna, which helps to widen the bandwidth of the LOOP walkie-talkie antenna and improve the LOOP walkie-talkie antenna's ability to receive signals with different polarizations.
