摘要：By integrating planar circuits, such as a microstrip line, and the rectangular waveguide w ith inductive posts onto the same substrate, the low -loss bandpass filter can be realized w ithout resort to tuning or mechanical mounting. How ever, the design and performances of the filter are limited by the conventional PCB process restrictions, such as constant via-holes diameter and material characteristics. In this paper, a single-substrate integrated waveguide bandpass filter operating in U-NII band is realized using thick-film technology
