Abstract
This paper proposes a new type of stub-loaded slotline resonat cell for exploration of a bandpass filter (BPF) with a tunable transmission zero (TZ). The circuit is constructed of a conventional uniform-impedance slotline resonator with a centrally loaded slotline stub. Based on Even-Odd theory, it can be observed that the proposed resonator has two resonant modes, the even and odd modes. And a finite-frequency transmission zero is also generated that can be individually controlled by the odd mode. Then a novel type of BPFs is realized using the proposed slotline resonator, which has a flexibly controllable TZ that can be individually tuned by the adjusting the odd mode. The simulation results validate the design flow well.
