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 (HEM₁₁₁, HEM_21δ and HEM_13δ) 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_11δ, HEM_21δ−like, HEM_21δ, HEM_12δ, HEM_13δ, HEM_14δ) in three impedance band and three CP bands. Different sense of CP is reported. The antennas operate in both C and X bands.
