Abstract: A Tri-Band I slotted rectangularpatch microstripantenna is presented in this paper .The antenna resonates at1.43 GHz, 5.16 GHz and 7.60 GHz frequencies. The antenna is fed with coaxial feed giving band widths of 10.52%, 7.20% & 30.83% for VSWR valuesless than 1.14.Theproposed antennacan be used for WLAN (Wireless Local Area Network) applications.
