Problems solved by technology

[0002] With the continuous advancement of urbanization, the population density of cities is getting higher and higher, and the communication system urgently needs to be expanded. The number of corresponding base station antennas is also increasing, resulting in increasingly scarce site resources for base stations. In the design of base station antennas , the design of dual-polarized and double-width H-plane antennas has attracted the attention of scholars and experts. However, due to the limitations of the antenna structure, it is largely difficult to solve the problem of antenna miniaturization due to the large size of the antenna.

At the same time, due to the inherent radiation performance of the dual-polarized double-width H-plane antenna at this stage, its radiation gain performance is greatly limited, and it is difficult to achieve high-gain and excellent performance.
