Linear-/Circular-Polarization Designs of Dual-/Wide-Band Cylindrical Dielectric Resonator Antennas
Xiao Sheng Fang,Kwok Wa Leung +1 more
TL;DR: In this article, a dual-mode cylindrical DRA was proposed for both linearly and circularly polarized cases, where the covariance matrix adaptation evolutionary strategy (CMA-ES) was used to determine the dimensions of the DRA.

Wideband Circularly Polarized Dielectric Resonator Antenna
TL;DR: In this paper, a quadruple strip feed cylindrical dielectric resonator antenna utilizing a pair of 90deg hybrid couplers is investigated experimentally, and the antenna is shown to deliver an impedance bandwidth (S11 < -10 dB) of 34.5%, from 1.75 to 2.48 GHz, and an axial-ratio bandwidth (AR < 3dB) of 25.9%.
