Abstract
In this paper, a miniaturized band-pass filter structure, which comprises the irises of small resonant aperture and L-type irises inverter, is proposed. Ridged circular aperture iris is chosen as an elementary resonator. L-type iris which is placed between two adjacent elementary resonators is newly proposed as impedance inverter in order to reduce longitudinal length of the proposed filter. The fabricated minimized filter has 400 MHz bandwidth at the 10 GHz center frequency and the whole size is reduced to 70 % in length compared to conventional filter.
