摘要

A novel transversal bandpass filter is proposed in this letter. Different from conventional two-order planar transversal filter, the proposed filter is a three-order planar transversal filter by incorporating microstrip dual-mode open-loop resonator and slot line resonator. Furthermore, by introducing source-load capacitive coupling, three transmission zeros are created to improve the selectivity of the passband and reject the unwanted signal above the passband. The measured result agrees well with the simulation. The size of the proposed filter is less than 0.15λ_g × 0.2λ_g, whereλ_g is the guided wavelength on the substrate.
