Journal ArticleDOI

Isolation Enhancement and Radar Cross Section Reduction of MIMO Antenna With Frequency Selective Surface

TL;DR: In this article, a new frequency selective surface (FSS)-based isolation technique is proposed for multiple-input-multiple-output (MIMO) antennas, and two FSS designs have been presented, and they are named as FSS and M_FSS.
Journal ArticleDOI

A Wideband Circularly Polarized Cubic Dielectric Resonator Antenna Excited With Modified Microstrip Feed

TL;DR: In this article, a cubic-shaped dielectric resonator antenna (DRA) with a new question-mark-shaped microstrip feed was proposed, which provides two orthogonal modes with a quadrature phase difference, hence generating circular polarization.
Journal ArticleDOI

Wideband Ring Dielectric Resonator Antenna With Annular-Shaped Microstrip Feed

TL;DR: In this paper, an annular shape microstrip feed is presented, which has been used to excite a hybrid mode in ring dielectric resonator antenna, achieving 10 dB impedance bandwidth of 66.72% at the center frequency of 5.35 GHz.
Journal ArticleDOI

An Investigation on Compact Ultra-Thin Triple Band Polarization Independent Metamaterial Absorber for Microwave Frequency Applications

TL;DR: The metamaterial property of proposed absorber unit cell dispersion diagram has been shown and it is shown that the absorber structure offers more than 80% absorptivity at different angle of incidence (up to 60°) under transvers electric and transvers magnetic polarization states.
Journal ArticleDOI

A Compact Zeroth-Order Resonating Wideband Antenna With Dual-Band Characteristics

TL;DR: In this paper, a composite metamaterial (MTM) antenna with dual-band characteristics is proposed, which consists of patch with series gap, meander line inductor, and a radial stub.
