Problems solved by technology

At present, low-frequency spectrum resources are very crowded, and it is difficult to meet the needs of future 5G communications. Opening up new frequency bands has become an inevitable choice for 5G. However, millimeter waves have unique properties such as rich spectrum resources, good orientation, and strong anti-interference capabilities. , has received more and more attention. Among them, the antenna at the front end of the millimeter wave transceiver system is particularly important. The performance of the antenna such as gain, bandwidth, and efficiency directly determines the quality of the system.

Conventional microstrip antennas have a narrow frequency band, which cannot meet the requirements of the 60GHz frequency band in the millimeter wave band, and the feeder has strong radiation loss, resulting in low efficiency of the entire antenna array
