Study of Different Pattern of EBG Structures for Dual Frequency Rectangular Notch Square Microstrip Antenna

Square Microstrip Antenna (SMA) with rectangular notch at its radiating side is designed and analysed for its dual frequency characteristics. Electromagnetic band gap (EBG) structures are employed by etching holes at the bottom side of patch. The EBGSMA also contains a reflector plane which is placed at 8.5mm distance from the patch. The variation in the properties of Square Microstrip Antenna (SMA) with rectangular notch having different patterns of EBG is studied.
