In this paper a simulated study of slot and notch loaded rectangular patch antenna is presented. This proposed antenna shows the tripple frequency band operation which is depends on the inserted slot and notch on the rectangular patch. It is found the proposed antenna resonates at tripple distinct resonance mode at 2.5GHz, 4.2GHz, and 5GHz for lower and upper resonance frequencies respectively. The designed antenna shows tripple frequency response nature with frequency ratio 1.68 and 1.190. The various characteristics of slot and notch loaded rectangular patch antenna gain (5.7dBi, 5dBi, 6.4 dBi), directivity (5.7dBi, 3.4dBi, 3.9dBi), efficiency (90%, 40%, 90%) and radiation pattern lobes are found in good agreement.
