Abstract
This paper presents the design of a novel aperture coupled cylindrical dielectric resonator antenna with linear polarization and circular polarization. The linearly polarized cylindrical dielectric resonator antenna (LP CDRA) with proposed aperture and microstrip feed line excites three hybrid radiating modes (HEM<inf>11δ</inf>, HEM<inf>21δ</inf>, and HEM<inf>13δ</inf>) in three impedance bands. The circularly polarized cylindrical dielectric resonator antenna (CP CDRA) with proposed aperture and flag-shaped feed line excites six different hybrid radiation modes (HEM<inf>11δ</inf>, HEM<inf>21δ-like</inf>, HEM<inf>21δ</inf>, HEM<inf>12δ</inf>, HEM<inf>13δ</inf>, HEM<inf>14δ</inf>) in three impedance bands and three CP bands. A different sense of CP is reported. The antennas operate in both C and X bands. © 2022, Electromagnetics Academy. All rights reserved.
