Summary:
A new type of compact microstrip line photonic band gap(PBG) structure employing T-type microstrip line for filter is presented. A miniature band rejection filter with four cells is simulated, fabricated, and measured. The filter with four proposed PBG structure exhibits band rejection characteristics (lower than -10dB from 23GHz~32GHz). The center frequency of stop-band is at 28GHz. The period of the PBG lattice is about 0.15e. The line length of the filter with PBG cell employing T-type micorstrip line was reduced to about 10.4mm, and its size was 14% of the conventional band rejection filter. The filter is very compact and much easier for fabrication and realization in MIC and MMIC.
