ABSTRACT:
A signal separator and bandpass filter that use plates with posts. The signal separator uses two bandpass filters to separate two signals of different carrier frequencies from one another. The bandpass filters each have a transmission line with the metallic plates disposed along its length. The number of plates and the distances between adjacent plates determine the bandwidth and the rejection capability of the filter.
