This article presents a multilayer multipermittivity (MLMP) ring dielectric resonator (DR) which is simultaneously used as a filter and an antenna, hence called dielectric resonator antenna filter. Multiple stacked layer of different permittivity along with the ring feature of DR gives a wideband response for antenna part with improved spurious response. In the presented MLMP ring DR, HEE11 and TE01 delta modes are used for antenna and filter element, respectively. As HEE11 and TE01d are orthogonal in nature that gives an independent control over filter and antenna characteristics. Measurement result reports an impedance bandwidth of 38.06% for dielectric resonator antenna (DRA) covering frequency range from 5 to 7.35 GHz for DRA and 3-dB bandwidth is 211 MHz covering frequency range from 5.82 to 6.03 GHz for dielectric resonator filter (DRF). The measured resonance frequency is 5.38 and 5.93 GHz of DRA and DRF, respectively.
