Design and Moisture Influence Analysis of a High Temperature Resistance FSS Radome

This paper presents a Ku-band frequency selective surface (FSS) radome design with a bandwidth of 1GHz, and the correctness of the design is verified through experiments. The microwave transmission performance of FSS radome decreases because of the moisture absorption of silicon dioxide-based materials. The test results show that the microwave transmission performance can be restored by drying for a long time.
