Wideband flipped staired pyramid dielectric resonator antennas

A wideband aperture coupled flipped staired pyramid shaped DRA is presented. An impedance bandwidth of 62% (S-11 < -10 dB) is measured. The proposed DRA has a stable broadside radiation pattern across the matching band. with an average gain of 6.5 dBi. Simulation results obtained from Fidelity give good agreement with measured results.
