Rectangular Dielectric Resonator Antenna With Corrugated Walls [PDF]
IEEE Access, 2019 A wideband and high-gain rectangular dielectric resonator antenna (RDRA) with corrugated walls is introduced. By generating corrugation in two opposite sidewalls of the RDRA, the radiation intensity from them compared to that of the top wall increases, which in turn will raise the boresight gain of the antenna.
