Abstract

Single layer and double layer adaptive FSS with ring slot units has been investigated in this paper. Ring slot FSS acts like band-pass filter. It can be used in antenna radomes. Lumped-element devices are loaded on the periodic units. Resonant frequency of the FSS depending on the lumped-element´ capacitance could shift in a specified frequency band. The bandwidth of the FSS with reflection loss below -10 dB can get to 10 GHz.
