In this paper, the authors presented a newly Photonic Band Gap (PBG) structures for microwave applications. This new type PBG structure is a two dimensional square lattice with each element consisting of a metal pad and four connecting branches. Experimental evidence is provided of the implementation of filter with wide band gap at higher cut off frequency (7GHz) for six cell lattice PBG structure and insertion loss S12 is -80.9dB. A new compact e-type PBG structure provided wide band gap at cut off frequency (3GHz) and transmission coefficient S12 -52dB that shows excellent agreement with results predicted by the theory.
