Abstract

A compact reduced size new electromagnetic bandgap (EBG) structure with the combination of AIEBG and multiple narrow slits in power plane is presented. Low on-set frequency is realized by concatenating 2 Ã— 2 high frequency unit cells into a low frequency EBG unit cell without changing the over all dimensions of the EBG. Newly designed EBG operates over a frequency band of 0.9 GHz to 3.5 GHz with a good isolation of better than -40 dB over the band with 2 Ã— 2 unitcells. The impedance of the structure is also presented, which is less than one ohm over the stop band of the EBG. Both the simulation and the measured results are compared and presented.
