In present days technology made things smaller and smaller. We have different application in microwave frequency range such as GSM, Bluetooth, and WLAN etc.in order to use this applications we need different antenna, but as technology is being advanced the demand of making an antenna which operates in all the above applications is required. To fulfill the demand of above stated antenna, a design of micro strip antenna which works under multi frequency of operation using serrated structures has been introduced. This antenna maintains a maximum gain of 8dB. The designed antennahas a small overall size of 13×13×0.67 cm, and operates over thefrequency ranges, 1.45 GHz,-1.85 GHz, 2.10–2.70 GHz, and 2.82–3.74 GHz suitable for GSM 1.8GHz, Bluetooth 2.4GHZ, WLAN 2.4 GHz and WiMAX 3.5 GHzapplications. Experimental results show that the antenna gives radiation patterns and good antenna gains over the operating bands.
