QUASI-LUMPED DESIGN OF UWB BPF USING SUSPENDED STRIPLINE

We propose a novel UWB bandpass fllter (BPF) design using the suspended stripline (SSL). The fllter composes of a low-pass and a high-pass circuit, both implemented by SSL structures. A notch response structure might be implemented to the fllter 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.
