A single feed compact micro-strip antenna is proposed in this paper. One L slit & one H slit are introduced on the right edge of the patch to study the effect of the slit on radiation behaviour with respect to a conventional micro-strip patch. An extensive analysis of the return loss, radiation pattern and efficiency of the proposed antenna is shown in this paper. For the optimize value of the slit parameters antenna resonant frequencies are obtained at 2.53, 4, 5.73 & 7.54 GHz with corresponding bandwidth 12.48 MHz, 37.97 MHz, 80.68 MHz, 230.67 MHz and return loss of about -17.4, -32.5, -12.4 & -29.7 dB respectively. The antenna size has been reduced by 75% when compared to a conventional micro-strip patch.
