摘要：

In this paper, a novel ultra wideband monopole antenna with frequency band-stop performance is designed and manufactured. The proposed antenna consists of a square radiating patch, and a ground plane with a cross-shaped slit and an inverted pi-shaped conductor-backed plane. The cross-shaped slit, increases the bandwidth that provides a wide usable fractional bandwidth of more than 125 % (2.86 GHz - 12.91 GHz). In order to create band-notched function we use an inverted pi-shaped parasitic structure in the ground plane, a frequency notch band of 5.11 GHz - 6.02 GHz has been achieved. Good VSWR and radiation pattern characteristics are obtained in the frequency band of interest. Simulated and measured results are presented to validate the usefulness of the proposed antenna structure for UWB applications.
