INVESTIGATION ON MICROSTRIP PATCH FRACTAL ANTENNA

Abstract A new design of Microsrtip patch fractal antenna for 2.5 GHz is proposed which possess an excellent size reduction possibility with good radiation performance for wireless applications like Wireless Local Area Network (WLAN). The design and simulation results of microstrip patch fractal antenna using Ansoft HFSS is presented which has S11 <-10 dB (VSWR<2). The antenna is designed based on the transmission line model with the input impedance of 50 ohm. The fractal geometry for the conventional antenna is generated up to second iteration. The results show that size reduction of 51.9% can be achieved as compared to conventional patch antenna
