Abstract:-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
(????????????(????) = 0.02, ???????? = 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 |????11| < −10 ????????with
resonating frequencies 1.53, 2.45, 3.47, 4.85 and 5.54 GHz. Formulation of the resonating frequencies is
also presented after inspecting the current distribution. To predict electromagnetic behaviour of the
antenna, structural parametric analysis is also carried out with the help of CST Microwave Studio.
