Compact Dual-Band and Wideband Aperture-Coupled Dielectric Resonator Antenna
A compact dual-band and wideband dielectric resonator antenna, the dielectric resonator is a combination of three rectangular joined with the side of a cylindrical with the same heights that is located in the center of FR-4 substrate, the proposed antenna was excited through the rectangular aperture coupled with a microstrip feed. Optimizing the design parameters results, in an impedance bandwidth of 14.7%, covering the range from 6.77 to 7.85 GHz in the lower band, and a relative bandwidth of 30.8% from 9.45 to 12.9 GHz in the upper band. The design has been developed and simulated using EM software “HFSS”.
