Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0040] As described in the background technology, the car antenna of the related technology includes a base, a shell and an antenna module. The shell is set on the base, and the antenna module is set on the base and located inside the shell. The design of the antenna module usually needs to be compatible with the vehicle's standard power system, and the vehicle's standard power system is generally 12 volts.

[0041] However, there are a variety of electronic devices in modern cars, including radios and low-noise amplifiers, which may require a 5-volt power supply to optimize performance and reduce power consumption. This makes the antenna module unable to adapt to some low-voltage components. For example, when the car's antenna pole is designed to adapt to a 12-volt power supply, and the car's radio is designed to adapt to a 5-volt power supply, it will cause poor signal reception quality or distorted audio output on the antenna pole and radio, and if the power supply does not match, it may cause an unstable power supply, which may cause electromagnetic interference and affect the performance of the radio and other electronic equipment, thereby reducing the applicability of the antenna module.

[0042] In response to the above technical problems, the embodiments of the present application provide an antenna and a car.
