Abstract

A novel compact dual band-notched dielectric resonator antenna (DRA) for ultrawideband (UWB) applications is proposed. Here, the bandwidth enhancement and the first band notch is realized by embedding a stub that is located to the hollow center of a U-shaped feedline simultaneously. By etching an inverted T-shaped parasitic strip at the back plane of an antenna that is surrounded by a dielectric resonator (DR), the second band rejection is created. By cutting a slot at the proper position on the ground plane, the width of the second band notch is controlled. The proposed antenna size is 12 × 30 × 6mm3 or about 0.124 ? × 0.31 ? × 0.062 ? at 3.1 GHz. The measurement results demonstrate that the proposed DRA provides acceptable radiation performances such as an ultra-wide impedance bandwidth of around 122% with two sufficient band rejections in the frequency bands of 3.22-4.06 and 4.84-5.96 GHz, high radiation efficiency, and nearly constant gain.
