This paper outlines a new polarization reconfigurable EBG (Electromagnetic Band Gap) antenna in the 60 GHz millimeter waves band. The proposed hybrid antenna is composed of a multilayer pyramidal DRA (Dielectric Resonator Antenna) exciting source covered with a FSS (frequency Selective Surface) superstrate. The device can switch between circular and linear polarization by a simple 45 ̊ mechanica...

Since antennas are strong radar targets, their cross section (RCS) reduction and radiation enhancement is of utmost necessity, particularly for stealth platforms. This work proposes the design a Fabry–Perot Cavity (FPC) antenna which has wideband low monostatic RCS. While in transmission mode, not only gain achieved, but beam also deflected elevation plane. Moreover, low-profile, i.e., cavity h...

Organic and inorganic materials such as perovskites, copper indium gallium diselenide, cadmium telluride, zinc tin sulfide/selenide (CZTS/Se) have been employed to capture unlimited sunlight through the photovoltaic effect. CZTS/Se is regarded most promising, environmentally friendly, abundant candidate with high absorption coefficient tunable bandgap for generation of solar energy. Superstrate...

The integration of metamaterial superstrate with high-quality cavity 3-poles stacked filter with patch antenna is presented. The metamaterial inspired behavior is obtained using split ring resonators (SRR) printed on the dielectric substrate Rogers 5880 which is located 12 mm from the top of the filter/antenna. The effects of the metamaterial structure on the vertically stacked filter/antenna p...
