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 (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.
