A very high efficiency Ultra wide band(UWB) hemispherical dielectric resonator antenna is simulated. The antenna is excited by commonly used feeding technique known as microstrip feeding. The dielectric resonator (DR) is inserted in the vertical edge of the substrate, which covers almost entire UWB bands(3.1 GHz to 10.6 GHz). A high impedance bandwidth of 3.74 GHz to 10.49 GHz is achieved in simulation...
A very simple low profile rectangular dielectric resonator antenna (DRA) is proposed in this paper. A partially printed metallic ground with two stepped section removed has been used. A stepped microstrip feed line is used to excite the DRA. The structure gives a very high bandwidth from 3.71GHz to 13.01 GHz with a band notch at 5.725 GHz. A T shape slot is used in the ground plane to create the notch...
