Abstract: Four elements aperture coupled cylindrical shaped Dielectric Resonator Antenna (DRA) circular array is proposed for generating reconfigurable polarization radiation patterns. In this array, all the elements are sequentially fed to generate circular polarization. The linear and circular polarizations of the DRA array are achieved by exciting the elements in different arrangements. The antenna provides wideband impedance matching (S11 ≤ -10 dB) of 39% (2.7 to 4 GHz) which covers RADAR band (2.7-2.9 GHz) and LTE bands (FDD 22 (3.41-3.59 GHz), TDD 42(3.4-3.6 GHz), TDD 43 (3.6-3.8 GHz)) for both linear and circular polarization radiation patterns. A feed network to accommodate these polarization reconfigurable patterns is under investigation and will be presented during the conference.
