Abstract
A broadband band-stop filter with T-shape diaphragms loaded in a rectangular waveguide is described to obtain good stopband characteristics. Single- and double-diaphragm loading structures are taken into consideration, followed by analysis of different physical dimensions on the whole characteristics. The stop-bandwidth of double-diaphragm loaded filter can cover the single TE10 mode operation band of standard rectangular waveguide WR-62 with large stopband attenuation. In addition, the filter can be used for waveguide mode suppression in modern high-frequency circuits with metal shielding.
