Description

Technical Field

[0001] The utility model relates to the technical field of walkie - talkie antennas, in particular to a coupled ultra - wideband dual - band walkie - talkie antenna. Background Technique

[0002] A walkie - talkie antenna is a device used to receive and transmit electromagnetic waves, and the key lies in optimizing the signal quality. Currently, the dual - band walkie - talkie antennas on the market all adopt two antennas in parallel, welded or riveted together. This structure will cause the weakening of the electrical signal flowing through the spring, and at the same time, it will cause the bandwidth to become narrow and the performance of the high - and low - frequency edges to be poor.

[0003] Therefore, those skilled in the art provide a coupled ultra - wideband dual - band walkie - talkie antenna to solve the problems raised in the above background technique. Content of the Utility Model

[0004] The purpose of the utility model is to provide a coupled ultra - wideband dual - band walkie - talkie antenna to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A coupled ultra - wideband dual - band walkie - talkie antenna includes an injection - molded outer shell. An inner - mold injection and a U - section radiator encapsulated by the inner - mold injection are arranged inside the injection - molded outer shell. A coupling spring is arranged inside the inner - mold injection. One end of the inner - mold injection is embedded with an insulator, a center pin is embedded inside the insulator, and a joint housing is sleeved on the outer wall of the insulator.

[0007] As a further scheme of the utility model: An aesthetic ring is arranged on the outer wall of the injection - molded outer shell.

[0008] As a further step of the utility model: The aesthetic ring is adhered to the outer wall of the injection - molded outer shell by strong glue.

[0009] As a further step of the utility model: An identification color ring is arranged on one end face of the injection - molded outer shell.

[0010] As a further step of the utility model: The identification color ring is adhered to one end face of the injection - molded outer shell by strong glue.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The walkie-talkie frequency band antenna of the present utility model adopts a spring with variable intercepts. By carefully adjusting the ratio of different intercepts, the influence of the narrowing of the frequency bandwidth can be minimized. Another frequency band adopts a coupling method, which can effectively reduce the interference to the walkie-talkie frequency band. The external walkie-talkie antenna spring is equivalent to a coil. Due to the existence of the coupling spring, the internal magnetic field will all pass through the center of the coupling spring, thereby changing the entire current direction, improving the final bandwidth, and further improving the bandwidth performance. Antennas with different frequency bands or specific functions are identified by color ring markings. Different colors represent different frequency ranges or types, which is convenient for users to identify during selection and installation, and helps to ensure that users select the appropriate antenna to match the working frequency of the walkie-talkie, thereby optimizing the communication effect.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model. Embodiment 1

A coupling spring 7 is arranged in the inner mold injection molding 6. One end of the inner mold injection molding 6 is embedded with an insulator 3. A center pin 4 is embedded inside the insulator 3. A connector housing 5 is sleeved on the outer wall of the insulator 3. Embodiment 2

[0018] Refer to Figure 1-2, this embodiment is based on the previous embodiment. The difference from the previous embodiment is that a beauty ring 8 is provided on the outer wall of the injection-molded housing 1. The beauty ring 8 is adhered to the outer wall of the injection-molded housing 1 by strong glue. An identification color ring 9 is provided on one end face of the injection-molded housing 1. The identification color ring 9 is adhered to one end face of the injection-molded housing 1 by strong glue.

[0019] Working principle: When the present utility model is in use, different frequency bands or specific function antennas are identified through the identification color ring 9. Different colors represent different frequency ranges or types, and users can identify them during selection and installation to select a suitable antenna to match the working frequency of the walkie-talkie. By adjusting the ratio of different intercepts, the influence of the narrowing of the frequency bandwidth can be minimized.
