Abstract

1. Bandstop filter with line elements for short electromagnetic waves, consisting of at least two resonators, an input line and an output line, in which the individual resonators are connected to one another via coupling lines, which have an electrical length deviating from lambda /4, if lambda is the wavelength of a frequency lying in the stop range, characterized in that characteristic impedance jumps are only envisaged in the input line and in the output line and the lengths of the input-coupling and coupling line sections deviate considerably from the value (2n-1) lambda /4 (n=1, 2, ...).
