A new type of compact microstrip line photonic band gap(PBG) structure employing T-type microstrip line for filter is presented. The center frequency of stop-band is at 15㎓. The line length of the filter with PBG cell employing T-type microstrip line was reduced to about 0.59㎜, and its size was 48% of conventional filter with PBG cell. The filter is very compact and much easier for fabrication and realization in MIC and MMIC.
