MICROWAVE PATCH ARRAYS WITH EBG- EFFECT OF CHANGING GAP

Sandhya Bhavsar, Bharati Singh

Patch antenna suffers from surface wave radiation and mutual coupling reduces antenna gain. To overcome this, EBG structures are used. Mostly used EBG structures are 2D type. Here proposing a uniplanar EBG showing the effect on mutual coupling and gain of antenna arrays. Changing the gap is studied to find the effect on bandwidth of operation.
