Analysis of large waveguide slot array antenna with dielectric cover using full wave method

摘要

The full wave design technology of waveguide slot array antenna is investigated with the simulation carried out by finite integration time domain method, and the dielectric cover is taken into account. Based on the CST software, large wave-guide slot array with more than 700 radiating slots is designed. Moreover, the radiation performance of the antenna with the dielectric cover is analyzed. The waveguide slot array antenna developed satisfies the technical requirements such as wide frequency band and low side lobe level. The research in this paper can promote the design method of waveguide slot array antenna accompanied with less experiment process and shorter design period.
