Microstrip antennas are the ones that fulfill most of the wireless system requirements. These antennas are widely used on base stations as well as handsets. The microstrip patch antennas have increasingly wide range of applications in the wireless communication system due to their great advantages. Planar Inverted L Patch (PILP) Antenna is a good candidate for achieving compact microstrip antennas. In addition to compact operation, this design is also suitable for dual-frequency operation. To satisfy the needs of certain wireless communication systems, it is required to design and develop the antenna arrays to obtain the increase in gain and enhancement in the bandwidth. The 2x1 element arrays of microstrip line fed shorted patch antennas are developed. The experimental study shows that the arrays offer considerable increase in gain and enhancement in the bandwidth.
