U Form Microstrip Patch Antenna for Ultra Wideband Communications

The present paper proposes a novel approach to enhance the performance and radiation efficiency of an Ultra-Wideband (UWB) miniaturized antenna. The latter consists of a rectangular patch supplied by a 50 ohm microstrip line and a rectangular slot inserted on the radiating element on stair treads between the feed and the antenna. This configuration allows a better adaptation. The study was carried out in UWB range of 3.1 to 16.7 GHz. The antenna's geometry and the results were acquired via an electromagnetic simulator (CST Computer Simulation Technology). The design and its performance are reviewed in this research paper.
