Millimeter-Wave Substrate-Integrated Edge-Grounded Rectangular Dielectric Resonator Antenna

A millimeter-wave substrate integrated edge-grounded rectangular dielectric resonator (DR) antenna (DRA) is proposed, which can reduce the fabrication error compared with the conventional DRAs fabricated by dielectric blocks. The dimension of DR is reduced by half due to the mirror effect of metalized holes. The DRA works is its TE
011
mode. It has an impedance bandwidth of 8% (23.8-25.8GHz) and a maximum gain of 4.67dBi.
