[0002] An antenna is a device used to transmit and receive electromagnetic waves and is widely used in wireless communications, broadcasting, television, radar and other fields.

[0003] When using existing antennas, it is difficult to use the inductive vibrator method, which makes the diameter of the vibrator itself thinner and winds it into a spiral line, increases the inductance of the vibrator itself, and shortens the length of the vibrator, resulting in lower radiation efficiency of the antenna, making it more difficult to better receive and transmit signals; and the environment may cause attenuation and interference to the signal. The existing technology is difficult to improve the signal strength received by the antenna, improve the signal quality, and ensure stable signal transmission, resulting in easy signal interruption and fluctuation. In addition, when some devices use signal boosters, it is difficult to install and disassemble the signal boosters, resulting in difficulties in later maintenance; The problem is that: when using existing antennas, it is difficult to reduce the impact on the antennas caused by wind and vibrations caused by trains, and it is difficult for some equipment to maintain the original position of the airbag during installation to minimize the impact on the antennas, and the practicality is relatively simple; when installing existing antennas, it is difficult to reduce the number of antenna installation connection points, reduce damage to concrete walls, reduce construction costs, and increase construction speed, and the practicality is relatively simple; Finally: When the existing antenna is in use, it is difficult to adjust the angle of the antenna cover to achieve lifting, which makes it difficult for the antenna to maintain the best working condition under different environmental conditions, increases the frequency and cost of equipment upgrades, and results in low signal reception sensitivity and signal-to-noise ratio.
