Abstract
This paper is aimed at developing a Sierpinski carpet fractal antenna with electromagnetic band gap (EBG) in the ground plane. This is designed using Rogers Duroid 5880 substrate, and validation of model is done using extensive simulations in CST MWS 2011. Several iterations are done and optimized to give the best result. The simulation results showed return loss of −22.25 dB at 8.592 GHz for third iteration. There is an enhancement of bandwidth by 209% from 75 MHz (conventional patch antenna) to 234.4 MHz using SCFA with EBG and directivity of 4.4 dB at resonant frequency. It shows reduction in size of antenna, and the proposed antenna size is 17.2 × 20.5 mm2. This antenna works well in X-band communication (8–12 GHz) for ultra-wideband imaging for medical application and weather monitoring radars in satellite communication.
