Abstract

A novel stepped-impedance resonator with a thin metal saucer is proposed in order to reduce spurious-response levels in a coaxial-line bandpass filter (BPF). In designing the BPF, the mode-matching technique is employed for fast and accurate calculation of coaxial-line discontinuities. A prototype BPF obtains a spurious-response level of less than -55 dB in the frequency band from 2f₀ to 9f₀, where f₀ is the pass-band center frequency.
