Abstract
A planar filter is proposed in which a plurality of striplines arranged next to one another on a substrate are supplemented by an overcoupling stripline which couples to one another two striplines which are not immediately neighboring. The length of the overcoupling stripline is an integral multiple of a half wavelength of the center frequency of the filter.
