Abstract:
A novel compact unidirectional UWB antenna is presented in this paper. First a novel planar omnidirectional UWB antenna with CPW-feed is designed. The antenna is composed of a half-elliptical disc with a small ground plane. A slot is inserted on the patch as a novel technique to improve the gain bandwidth of the antenna at higher frequencies is presented. The omnidirectional antenna shows UWB matching and gain bandwidth of 2 GHz to 6.5 GHz. Furthermore, to make the radiation pattern of the omnidirectional antenna unidirectional, a rectangular shape metallic reflector without bottom wall is used on the backside of the antenna. The unidirectional antenna with a total dimension of 0.52λm x 0.33λm x 0.18λmm wavelength of the minimum operating frequency) has a matching bandwidth of 1.5 GHz to 7.7 GHz with a gain of 5 dBi to 10.2 dBi over 1.7 GHz to 6.5 GHz, and flat group delays of less than 1 nsec. To validate the proposed design, the antenna is fabricated, and measured results are compared with simulations.
