Abstract
[Problem] To provide a cross coupled band-pass filter that reduces a loss of a signal due to a dielectric loss and enables a resonance frequency to be easily changed.[Solution] A cross coupled band-pass filter of the present invention includes an input waveguide, an output waveguide, and three or more stages of resonators that connect the waveguides together, in which the three or more stages of resonators is formed using a filter element, one or multiple pairs of resonators of the three or more stages of resonators adjoin via a shared tube wall and include an opening in the shared tube wall, an antenna that connects the one or multiple pairs of resonators together in the opening, and one or more stages of unconnected resonators between the one or multiple pairs of resonators in a waveguide path of electromagnetic waves.
