专利汇可以提供Stop band filter专利检索，专利查询，专利分析的服务。并且A waveguide band-stop filter utilizes a sequence of capacitive irises to form a plurality of resonant circuits connected in tandem. In the disclosed embodiment the filter is constructed of two sets of plates having iris-defining apertures of different sizes assembled to form a laminated structure with the plates disposed in alternating sequence. The filter is dimensioned larger than the waveguide but is of relatively short length.，下面是Stop band filter专利的具体信息内容。

权利要求

1. A narrow band band-stop filter for use with a waveguide having dimensions a and b and comprising: a first set of relatively thin plates respectively defining a first set of iris-defining apertures having an aperture dimension c, a second set of relatively thin plates respectively defining a second set of iris-defining apertures having an aperture dimension 1, said aperture dimension 1 being larger than said aperture dimension c and larger than the waveguide dimension b, said first and second sets of plates all being of approximately the same individual thickness t and being disposed in alternating sequence forming corrugations; an aperture difference dimension p being defined as: p 1- c/2 wherein the stop bandwidth is a function of the ratio: 4t2/bp and the ratio t2/p is caused to be made small by constructing the plates on the order of 0.1 inches thick or smaller and making the p dimension on the order of a quarter wavelength at the center frequency of the stop band, and means coupling the filter to separate waveguide sections.
