Problems solved by technology

In the microwave and millimeter wave frequency band, the design of dielectric resonant antenna can be realized by using traditional microstrip line technology, but when working at high frequency, the microstrip device has large spatial parasitic radiation and large loss, which directly affects the performance of the antenna

On the other hand, traditional metal waveguide technology can also be used to realize the design of dielectric resonator antennas, but when working at high frequencies, the antenna volume is very small, and the design of dielectric resonator antennas using traditional waveguide technology requires high processing accuracy And expensive processing costs. At the same time, it is difficult for this form of antenna to be directly integrated with the system circuit without gaps. After the processing is completed, cumbersome debugging is required, which increases the design cycle and design cost.
