Compact UWB frequency notched antenna

Abstract

The designed antenna will be a patch antenna which consists of a conductive sheet of metal mounted over a large sheet of metal called the ground plane with a substrate separating the two. Notched bands are WLAN and WiMAX. V shaped patch was then chosen and modified to an arrow shaped patch to give the optimized results operating on the entire UWB region with considerable return loss. The frequency notch prevents the operation of the antenna at a particular range of frequency, hence minimizing interference from other systems. There are numerous methods for introducing the notch but most common is inverted C-shaped slots in the UWB patch to get the notch features as output and also wavelength resonators to introduce notch in UWB band. The designed antenna is simulated on a software High Frequency Structural Simulator 13.0 simulation software by Ansoft.
