Abstract
A filter according to the present disclosure includes input means for inputting a first polarization signal and a second polarization signal that are input from an antenna. The filter includes output means for outputting a first output signal corresponding to the first polarization signal and a second output signal corresponding to the second polarization signal, the first and the second output signals having been subjected to filter processing for making a desired frequency electric signal of each of the first and the second polarization signals pass through the first and the second output signals, respectively. The filter includes a resonator group that excites a first excitation mode and a second excitation mode perpendicular to each other by the input first and second polarization signals, whereby the output means outputs the first and the second output signals corresponding to the first and second polarization signals, respectively.
