摘要：
A suspended stripline (SSL) bandpass filter using a hybrid transmission line stepped impedance resonator with a transmission zero (Tz) in the higher band is proposed. The novel resonator consists of a thin inductive strip, a set of hybrid transmission lines and patchlike capacitive elements, a coupled electromagnetic field to the input lines and adjacent resonators. The characteristics of the HTLSIR have been analysed clearly. Moreover, a novel non-resonating node is introduced to generate a Tz, its position can be adjusted by changing its parameter. A detailed discussion of this effect is given, and a sample filter is designed, fabricated and tested. Both experimental results agree well with the simulations.
