In this article, an analysis of modified version of the Scarecrow antenna with boat shaped ground for wideband application is presented. The proposed monopole configuration consists of composite shaped radiating element and truncated ground plane which is modelled on FR-4 substrate (tan⁡(δ)=0.02,ε_r=4.3)The overlapping and tuning of resonating modes is achieved by augmenting composite slot on top edge of the boat shaped ground plane. The electromagnetic energy is delivered to radiating patch through the feed line which is connected with SMA connector. The proposed antenna has exhibited the fractional bandwidth of 128.76 % from 1.3 GHz to 6 GHz for |S_11 |<-10 dBwith resonating frequencies 1.53, 2.45, 3.47, 4.85 and 5.54 GHz. To predict electromagnetic behavior of the antenna, structural parametric analysis is also carried out with the help of CST Microwave Studio.
