SPECTRAL CHARACTERISTICSOF STEP-BENDED BAR IN A RECTANGULARWAVEGUIDE

摘要

Waveguide bandstop and notch filters are widely used microwave devices. One of notch filters is in the focus of this paper. It is a stepped conductor in a rectangular waveguide cross-section (inset in Fig. 1). Such a filter.provides narrow-band reflection of the TE_(10) wave at a desired frequency of the operating frequency range. It can be used both as a section of a bandstop filter and as a notch filter itself.
