This paper reports a detailed experimental analysis on the effect of forbidden bandgaps of planar metallo-dielectric electromagnetic bandgap (EBG) structures as ground plane of a half wavelength linear resonator. It is observed that the resonator with metallic square and triangular lattice as ground plane results in resonance shifting to higher values whereas, on patterning negative structures of the said lattice which we mention as dielectric lattice in this paper, did not result in any appreciable change. Simulation and experimental results illustrate appreciable increase in quality factor and decrease in insertion loss for metallic EBG on the ground plane, while marginal reduction in insertion losses and increase in quality factor has been obtained with dielectric lattice.
