Abstract

A compact super-wideband antenna which is asymmetrically fed by a coplanar waveguide (CPW) line is investigated in this paper. The proposed antenna is composed of a rectangular patch and a modified ground plane. The ground plane with an L-shaped structure and a notch helps to improve the impedance match performance. The simulated result shows that the antenna has two frequency bands covering 2.07-2.22 GHz and 3.5-50 GHz with VSWR <; 2. The antenna radiation pattern is nearly omni-directional over the whole operating band. Details of the antenna design and results are presented.
