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