However, due to the limitations of the working frequency band and radiation aperture of various helical antennas, the longitudinal size of the antenna is compressed, and the lateral size of the system is widened, which reduces the working bandwidth of the antenna system, so that the antenna itself presents point-frequency working characteristics. In order to broaden the working frequency band of the system, Generally, it is necessary to consider adding a more complex broadband matching network inside the equipment, which makes the overall layout of the equipment and the cost of research and development remain high.
At present, all kinds of mobile terminal system terminal antennas, especially all kinds of miniaturized and miniaturized UAV measurement and control antennas are developing towards miniaturization, compactness, and lightweight installation, but existing antennas cannot meet the requirements of miniaturization and miniaturization Demand for high-speed mobile concealed installation environments such as drones
