Abstract
Official abstract text for this publication.
A millimeter waveband filter is provided with a resonator formed by a pair of electric wave half mirrors in a transmission line of a waveguide allowing electromagnetic waves in a predetermined frequency range of a millimeter waveband to propagate in a TE10 mode, and allows frequency components centering on the resonance frequency of the resonator to pass therethrough. A high-pass filter which has a transmission line reduced in size so as to have a cutoff frequency matching an upper limit of a lower rejection band of a filter passband is formed in a transmission line between the end of the waveguide and the electric wave half mirror, thereby increasing the attenuation of the lower rejection band.
First claim
Opening claim text (preview).
The invention claimed is: 1. A millimeter waveband filter comprising: a waveguide which has a transmission line allowing electromagnetic waves in a predetermined frequency range of a millimeter waveband to propagate from one end to the other end in a TE10 mode; a pair of electric wave half mirrors which have characteristics to transmit a part of the electromagnetic waves in the predetermined frequency range and to reflect a part of the electromagnetic waves, are arranged to face…
