Simulation study of a simple structured filter-antenna combination using a dielectric resonator (DR) is presented in this paper. The coupling between the input and output ports of the filter occurs due to alumina ceramic acting as DR and same DR is utilized as an antenna. The proposed filtering dielectric resonator antenna (DRA) provides good impedance(More)
A dual segment cylindrical dielectric resonator antenna with metamaterial superstrate is presented in this paper. The metamaterial cover acting as a converging lens is sharply increasing the gain of the proposed antenna and is also responsible for increasing the bandwidth. The proposed antenna is having a better impedance matching (less than -10 dB return(More)
