Slotted patch antennas with EBG structure for ISM band

A slotted patch antenna is designed with Electromagnetic Band gap (EBG) structures inside patch for ISM band. The performance parameters of the presented antenna are then compared with the slotted patch antenna and slotted patch antenna with EBG structure inside patch. It is realized that the bandwidth requirement is fulfill than the normal patch antenna, with reduction in back lobe. This antenna is operating in the frequency band 2.4GHz. to 2.48 GHz which is one of the most usable bandwidth regions for wireless applications such as Wi-Fi outdoor, WLAN, and many more. The proposed antenna achieves return loss -39dB. Built in FR-4 material.
