DUAL-BAND FREQUENCY SELECTIVE SURFACE WITH MINIATURIZED ELEMENT IN LOW FREQUENCIES

Abstract

In this paper, we propose a dual-band frequency selective surface (FSS) in low frequencies with miniaturized element. A dual- concentric square element with two difierent slot sizes is constructed to realize dual-band passband responses. Each passband is realized by a square slot structure. Besides, we reduce the slot sizes to make the element miniature and compact. Based on this technique, a dual- band FSS with miniaturized element in low frequencies is designed. Both the simulation and experiment results show that such a FSS owes its advantages to miniature element, stable performance with various incident angles and difierent polarizations, which is suitable for dual- band shipboard communication.
