Antennas come in many types and styles, among which antennas are more widely used in the field of vehicle communication systems. Because vehicle communication systems require extremely high stability, a good low sidelobe antenna for vehicle communication systems is particularly important.
[0003] For example, application number: CN202110367887.8 involves a low sidelobe antenna used in a vehicle communication system. Among them, the low sidelobe antenna includes an antenna body and a coaxial feeding terminal. The material of the antenna body is metal. The antenna body is defined to have an up and down direction. The antenna body is provided with a feeding cavity and a resonant cavity from bottom to top. The antenna body is also provided with a feeding slot connecting the feeding cavity and the resonant cavity, and a plurality of radiation slots connecting the resonant cavity and the outside world. The plurality of radiation slots are all located on the upper surface of the antenna body and are symmetrically distributed about the feeding slot; the coaxial feeding terminal is passed through the antenna body and extends into the feeding cavity. The technical solution of the present invention enables the low sidelobe antenna to be fed without the need for a power divider, thereby simplifying the structure of the low sidelobe antenna; and it also enables non-uniform amplitude to be obtained relatively easily while maintaining the same-phase excitation of multiple radiation slots by simply adjusting the size and position of the radiation slot.
[0004] Based on the prior art, it is found that the existing low sidelobe antenna used in the vehicle communication system is not equipped with multiple groups of antenna array adjustment devices, which is not conducive to the adjustment of signal transmission and reception. At the same time, it cannot assist in better reducing interference. There is no multi-point independent positioning device, and the multiple radio wave polarization adjustments required for automobile communication cannot be achieved, resulting in a reduction in the radio wave loss control effect. There is no low sidelobe antenna monitoring device, and real-time monitoring of low sidelobe signals through analog signals cannot be achieved. It is not stable enough and can easily cause deviations in signal transmission. At the same time, it causes signal obstruction, resulting in the weakening of the main lobe signal.

During the backward movement of the telescopic adjustment frame, the inclined surface on the rear side of the telescopic adjustment frame will squeeze the linkage hemispherical column, causing it to drive the positioning block to slide outward until the positioning teeth on the positioning block are engaged with the positioning teeth. The entire process is driven by an electromagnet, which has a very fast response and can quickly release the rotation driving force of the adjustment tube while fixing the angle of the adjustment tube. By setting four groups of adjustment tubes with the same structure, the four array antennas can be independently adjusted without interfering with each other, and independent polarization adjustment can be effectively achieved. This is suitable for different signal processing methods and is more practical. The multi-channel antenna mode can ensure stable communication of the car around the clock. At the same time, four independently adjustable array antennas can be used to effectively reduce electromagnetic wave losses. BRIEF DESCRIPTION OF THE DRAWINGS
