Abstract :
In this paper, we propose a UWB bandpass filter composed of periodically-installed metallic posts in a rectangular waveguide, and study the basic behaviour both theoretically and experimentally. From the simulation, the wide passband from 5.95 GHz to 13.9 GHz and the well-suppressed out-of-passband were obtained, which results were verified experimentally. For the design of UWB response, we also study the important structural parameters of the filter.
