Sandwiched frequency selective surface (FSS) is proposed as an additional reflection for a dual-frequency reflectarray system. The range of phase depends on the substrate thickness sensitively. Usually, tradeoff between smooth linear level and wide needed, especially By inserting FSS ground plane reflecting element layer, band provided. For higher band, layer plane. lower it transparent changed...

A new dual-polarized antenna loading frequency-selective surface (FSS) is proposed for 5G wireless local networks (WLANs) application. The antenna consists of two orthogonal bow-tie dipoles and a ground plane. A new wideband FSS is designed comprising ring-slot connecting rectangular slots. The reflection coefficient of wideband FSS is less than 0.9 from 4–6.5GHz. The phase of reflection coeffi...

Enhancement of electromagnetic performance of A-sandwich radome using aperture-type Jerusalem cross frequency selective surface (FSS) is presented. The Jerusalem cross FSS array is embedded in the mid-plane of the core of Asandwich radome to enhance the EM performance parameters over the entire Xband. For modeling the Jerusalem cross FSS embedded radome panel and evaluation of its EM performanc...

In this paper, we present a novel approach for improving the bandwidth of a microstrip patch antenna using Jerusalem crossshaped frequency selective surfaces (JC-FSSs) as an artificial magnetic ground plane. The invasive weed optimization (IWO) algorithm is employed to derive optimal dimensions of the patch antenna and JC-FSS element in order for the whole structure to work at 5.8GHz with consi...

In this paper, an UWB-MIMO antenna with frequency selective surface (FSS) decoupling structure is proposed. To realize antenna system miniaturization and integration, silicon material is applied as substrate. The proposed antenna becomes a very compact construction with dimension of 38.2 × 26.6 × 0.4 mm. The proposed broadband FSS unit consists of four split rectangles and one I-shaped strip. T...

Airborne ultra wideband (UWB) impulse-radiating antennas (IRAs) present an especially large radar cross section to X–band radar. To mitigate this problem, we have numerically and experimentally investigated the use of a frequency selective surface (FSS) as a broadband filter to reflect X–band radar while transmitting lower-frequency UWB signals without loss or dispersion. We present here result...

The surface wave losses in the patch antenna reduces the bandwidth and gain of the patch antenna. This problem is overcame by use of frequency selective surface. the FSS has a variety of applications in antennas. The FSS is constructed with periodic arrays of metallic patches of arbitrary geometries or slots within metallic screens. FSS geometries are designed by rings, square loops and fractal...
