loss, improved impedance bandwidth and gain. Figure 3 shows the measured radiation patterns for the
proposed microstrip slot antennas 1, 2 and 3 (MSSA 1, MSSA 2 and MSSA 3) with co-polar and
cross-polar characteristics. The radiation patterns are measured and plotted at respective resonant
frequencies 3.51 GHz and 4.52 GHz for MSSA1, 3.81 GHz and 5.16 GHz for MSSA 2 and 2.22 GHz
