Abstract

In the current paper, mono and multi EBG structures for wider bandwidth are presented. For every EBG mentioned in this paper, metallic patches of regular shapes are selected as unit elements and these patches are altered to get additional inductance and capacitance which provides lower cut-off frequency and large bandwidth. The surface wave attenuation of EBG structures are juxtaposed with conventional EBG of mushroom type. The variation of transmission response due to unit element size, via diameter and distance between unit elements is shown. Out of these proposed EBG’s the square patch is small, the fractal EBG has wider bandwidth. The square patch with mono disconnected loop type slot and the fractal are multi band. The designing of microwave circuits and the antennas can be done using these EBGs.
