ABSTRACT In this paper, we present an equivalent circuit model of a uni-planar electromagnetic bandgap (EBG) structure. The equivalent circuit is developed by the combination of lumped element representation of distributed elements. The EBG structure is coupled to the transmission line and the coupling is modelled by a capacitor between the structure and the transmission line. The circuit simulated results match well with the electromagnetic simulation results.

ABSTRACT In this paper, a compact defected ground mushroom electromagnetic bandgap (DG-MEBG) structure is presented. Compactness is achieved by employing a DG in the conventional MEBG. DG-MEBG exhibits a low pass transmission response with a cut-off frequency of 4.2 GHz and wide stop band up to 17 GHz as against a cut-off frequency of 10.4 GHz observed in a conventional MEBG. Thus the proposed DG-MEBG is 60% compact in comparison with a conventional MEBG structure. The measured results show a very good agreement with the simulated ones.
