This paper presents a polarization insensitive frequency selective surface (FSS) based on concentric ring slots with five closely spaced passbands. The proposed FSS unit cell contains five ring slots coupled with a supplementary innermost ring slot.

In this paper, a tunable triband frequency selective surface unit cell based on varactor-loaded split ring slots is presented. By using the third resonant mode, a considerable mutual coupling reduction between adjacent ring slots is obtained ensuring

In this article, a novel approach to design low-profile miniaturized frequency-selective surfaces (FSSs) is proposed. The effective miniaturization of the FSS elements, based on square-ring-slot resonators, is accomplished by reactively loading the F

An active frequency selective surface (AFSS) with reconfigurable tunable and switchable properties is studied in this Letter. The AFSS unit cell consists of a split ring slot resonator loaded with a varactor diode. The proper biasing of the varactor

A leaky-wave structure (LWS) based on two stacked spiraphase-type reflectarrays (RAs) is analysed in this paper. Each RA contains capacitively loaded ring slot elements arranged at the nodes of a square periodic grid. The proposed LWS performs freque

This letter presents a dual-frequency reflectarray (RA). This RA is capable of forming two differently oriented main lobes with the same sense of circular polarization in the directions determined by the reflection elevation angles $\theta _{01}$ and
