F-slot dual bands EMSA for wireless communication
The microstrip patch antenna modiflcations have been being conducted over approximately four decades by different simulation tools. In this paper, an elliptical microstrip antenna (EMSA) is considered as a reference one and the introduction of an F-cut on it has brought improvements in the various parameters in both the operating bands with the centre frequencies of 3.6 GHz (S-Band) and 5.3 GHz (C-Band) covering the wireless interoperability microwave access (WiMAX) and wireless local area network (WLAN) fields respectively. The put forth elliptical patch antenna at Rogers RT /duroid 5880 simulated by HFSS 13 can be used for the wireless fidelity (WiFi) applications also. The proposed antenna has exhibited the return losses of −36.5 dB and −23 dB and the wider radiation pattern with the maxima of field strength being approximated 24 dB and 21.83 dB with appreciable gain of 6.3 dB and 4.1dB at 3.6 GHz and 5.3 GHz, respectively.
