Abstract :
In this paper, a compact flexible band pass filter (BPF) based on substrate integrated circular cavities (SICC) is proposed. SICC works on TM modes and has advantages of high quality factor and good design flexibility. Filters are made from cylindrical cavities integrated into a planar substrate and are fed by microstrip lines through coupling slots. First-order and third-order filter are presented. This filter with simple structure exhibits an insertion loss of 0.85dB at center frequency 18GHz, and a 3-dB bandwidth 14.4%.
