An Angularly Stable Dual-Band FSS With Closely Spaced Resonances Using Miniaturized Unit Cell
TL;DR: In this paper, a dual-band frequency selective surface (FSS) with closely spaced resonance is presented, which comprises of meander lines printed on a single-layer dielectric substrate to provide dual stopband characteristic.

TL;DR: In this paper, an optically transparent broadband microwave absorber has been developed, which is constructed of the patterned resistive films of an indium-tinoxide on flexible substrates, such that the structure exhibits broadband absorptivity (above 90%) from 4 to 17.20 GHz (covering C, X, and Ku bands).
Journal ArticleDOI
Bandwidth-enhancement of an ultrathin polarization insensitive metamaterial absorber
TL;DR: In this article, an ultrathin polarization insensitive microwave metamaterial absorber is discussed, which consists of a periodic array of swastika-like structure printed on FR4 dielectric substrate backed by copper ground.
Journal ArticleDOI
Substrate Integrated Waveguide Cavity-Backed Dumbbell-Shaped Slot Antenna for Dual-Frequency Applications
TL;DR: In this paper, a novel dumbbell-shaped slot along with thin substrate integrated waveguide (SIW) cavity backing is used to design dual-frequency slot antenna, which exhibits unidirectional radiation characteristics, high gain, high front to back ratio (FTBR) at each resonant frequency while maintaining low profile, planar configuration.
Journal ArticleDOI
Polarization-Insensitive Broadband Multilayered Absorber Using Screen Printed Patterns of Resistive Ink
TL;DR: In this paper, a broadband polarization-insensitive multilayered microwave absorber using resistive ink has been presented, where each layer consists of periodic arrangement of resistive patterns printed on a low-cost FR4 sheet.
