Microsrip Fed Dielectric Resonator Antennas

The dielectric resonator (DR) has primarily been used in microwave circuits, such as oscillators and filters. As compared to the microstrip antenna, the dielectric resonator antenna has a much wider impedance bandwidth. Since the Dielectric resonator antennas (DRAs) are fabricated from low loss, temperature stable microwave dielectric materials and has negligible metallic loss, it is highly efficient when operated at millimeter wave frequencies. The Resonant frequency of DRA is a function of size, shape & permittivity.The bandwidth of DRA depends on parameters such as the excitation method, shape, dimensional parameter & dielectric constant of DRA material. This book introduces the two-segment rectangular DRA in side by side form. The structure composed of two different rectangular DRA, which separated by a Perfect E plate.
