Quasi-lumped design of UWB BPF using suspended stripline

[[abstract]]We propose a novel UWB bandpass �lter (BPF) design using the suspended stripline (SSL). The �lter composes of a low-pass and a high-pass circuit, both implemented by SSL structures. A notch response structure might be implemented to the �lter by embedding a resonant slotline. The quasi-lumped elements circuit models were developed to analyze these circuits' performance. Experiments were conducted, and good agreements were observed between the measurements and simulations
