A dual polarized triple band microstrip antenna with symmetrical multiple rectangular slots has been studied. First, the rectangular patch has been fed at a fixed point and the effect is noted. Further, a symmetric plus-shaped slot has been inserted onto the patch and its effect is studied. The length of the plus shaped slot is increased and its effect on the lower order modes is observed. Next, the feed-point location is changed to obtain optimum radiation pattern. The operating frequency range of the antenna is from 0. 2-1. 5Ghz.
