This paper elucidates the comparison between simulated and fabricated results of the designed frequency reconfigurable microstrip patch antenna which is used to operate on wireless application. The designed antenna is compact in size of 40 X 40 X 1.67 mm3 including the ground plane and both antenna structures are designed on FR-4 substrate of thickness h=1.6 mm. By using PIN diode switching property, designed antenna shows reconfigurable characteristics which is working for two distinct frequency. This antenna is working for four frequency bands after linking with diode, two for ON state and two for OFF state. In ON state it has resonant frequencies 5.55GHz and 6.5GHz while in OFF state it working for 5.65GHz and 6.6GHz. With the help of electromagnetic (EM) simulation software, designed structures were simulated and using VNA results like vswr, return loss are achieved.
