In wireless communications, there are several types of microstrip antennas, the most common of which is microstrip printed antenna. Printed antennas are also relatively inexpensive to manufacture and design because of simple 2D physical geometry. A single feed single layer compact rectangular microstrip antenna is proposed in this paper. Two L slits are introduced at the right edge of the patch to reduce the resonant frequency. For the proposed antenna resonant frequencies are obtained at .9 GHz, 1.76 GHz, 2.04 GHZ, 3.53 GHZ and 4.82 GHz with bandwidth of 11.41 MHz, 12.74 MHZ, 20.56 MHz, 20.37 MHz, 38.85 & return loss about - 15.23, -13.83, -28.84, -28.1 &-17.21 dB respectively.
