Abstract
This paper presents a stacked dielectric resonator antenna with a drilled hollow cylinder. The antenna has thirteen dielectric layers with different permittivity (ɛr1 = 12 and ɛr2 = 4.4) on a FR4 epoxy substrate having a dielectric constant of 4.4 with 0.8 mm thickness. It uses one hollow cylinder of diameter 0.8 mm which is drilled at right bottom corner in a design of the proposed antenna. The analysis is performed on 3D EM simulator high-frequency structure simulator. The wide improvement in bandwidth of the DRA with a drilled hollow cylinder is presented with the help of the proper excitation and selection of the resonator parameters based on a −10 dB reflection coefficient.
