A novel cup-shaped dielectric resonator antenna (DRA) geometry based on inverted hemispherical dielectric resonator antenna (HDRA) is proposed and investigated. The material used for investigation is Rogers TMM10, which is a ceramic thermoset polymer composite material having a dielectric constant of . The cup-shaped geometry offers a wideband of 83% impedance bandwidth for...
In this paper, a novel cheeseholes type Hemispherical Dielectric Resonator Antenna (HDRA) is proposed. The name has been coined due to the similarity it draws in appearance with a Swiss cheese cube. Here, array of slots are drilled periodically along the three Cartesian axis of the HDRA. In doing so, the bandwidth of operation increases from 10.4% to 25% with a gain of 6.2 dBi at the resonant frequency...
