Summary:
A new compact band-notched dielectric resonator antenna (DRA) for ultra-wideband (UWB) applications is presented. The antenna elements consist of a thin monopole printed antenna loaded with rectangular dielectric resonator (RDR) which is housed into a dielectric substrate, an I-shaped parasitic strip, and a slot on the ground plane. Here, to realize band-notched characteristic, an I-shaped parasitic strip is placed on the top of DRA. By cutting a slot on the ground plane, impedance matching performance is improved. The proposed antenna provides an impedance bandwidth of around 98 %, excellent omni-directional radiation patterns with low cross polarization, nearly constant gain, and high radiation efficiency across the whole desired frequency band.
