Abstract: This article deals with the various designs of a novel compact microstrip fed UWB antenna to investigate the corresponding return losses of different structures. The dimension of the designed antenna is 33 x 19 x 1.9 mm3 with FR4 substrate and it can be operated from 2.846 – 11.7458 GHz. The effects of varying the structure of antenna are to exhibit the investigation of corresponding return losses. Different structures of antenna are simulated in Ansoft HFSS simulator. The results of return losses and radiation patterns are explored with the ultra wide band (UWB) rectangular Stair slot antenna. The modified structure of antenna shows the minimized return loss with an enhanced bandwidth that satisfies good UWB characteristics. Antenna performance can also be explored from the radiation behavior of the antenna which is relatively omni-directional pattern for rectangular Stair slot antenna
Keywords: UWB, rectangular stair slot antenna, return loss, Bandwidth enhancement, radiation pattern, microwave imaging.

Scope of the Article: Micro Strip Antenna
