In a millimeter waveband filter, electric wave half mirrors are provided in transmission lines of a first waveguide configured to allow electromagnetic waves in a predetermined frequency range of a millimeter waveband to propagate in a TE10 mode and a second waveguide connected to the first waveguide in a state where one end of the second waveguide is inserted into the first waveguide, and the waveguides are relatively moved to vary the interval between the electric wave half mirrors, thereby changing a resonance frequency. The first waveguide is a square waveguide, and the second waveguide is a ridge waveguide in which the outside thereof is a rectangular shape at a predetermined interval with respect to the inside of the first waveguide and a sectional shape of a transmission line has a central portion having a height smaller than both side portions.


The millimeter waveband filter includes: a transmission line that is formed by a waveguide which propagates electromagnetic waves with a predetermined frequency range of a millimeter waveband from one end to the other end in a TE10 mode; and a pair of radio-wave half mirrors that are disposed opposite each other with a space interposed therebetween so as to block the inside of the transmission line and have planar shapes and a characteristic of transmitting a part of the electromagnetic waves with the predetermined frequency range and reflecting a part thereof. In the electromagnetic waves incident from the one end side of the transmission line, a frequency component centered on a resonant frequency of a resonator, which is formed between the pair of radio-wave half mirrors, is selectively output from the other end of the transmission line.
