Abstract
This paper is aimed at proposing a novel printed microstrip-fed slot antenna suitable for wireless ultra-wideband (UWB) communication systems. The proposed antenna has been designed for operating at GHz frequency band. The synthesis of the antenna is carried out by means of parametric study of the main parameters. The result is a printed stepped-circular-shaped slot antenna exhibiting a good impedance matching with different tuning stubs. To demonstrate the effectiveness of the proposed UWB antenna, the results from numerical validations and experimental tests are presented and discussed.
