In this paper a quad band micro strip patch antenna have been design and analysis. Paper is simulated for mobile communication mainly. In this we have used multiple I slots to increase multiple resonant frequencies, by which we can enhance radiated power and total radiation from the patch. There are many feeding technique are available but we have used micro strip feed. Four resonant frequencies created and can we used for four different applications. By slotting impedance matching and radiation increment can be done. This antenna can be used for most of the L band applications. On these four resonant frequencies value of return loss should be less than -10dB, which is achieved. Frequencies on which it can work are 300MHz, 1500MHz, 2300MHz and 2700MHz. And their respective return losses are -58dB, -36dB, -40dB and -35dB. Thickness of the antenna is 1.6mm & value of VSWR of the antenna is found close to two, which is desired. Size of the patch is 40*50 which is compact & durable due to simple design.FR4 substrate is used due to availability. Antenna is simulated & analyzed by FEKO simulation software which works on the principle of method of moment.
