Abstract
A high-frequency circuit device solves problems caused by a spurious mode reflection generated at a part where propagation of a spurious mode wave is prevented, with the result that propagation of the spurious mode wave such as a parallel plate mode wave is blocked. In the arrangement of the high-frequency circuit device, a leakage spurious mode wave radiates from a transmission line including at least two parallel planar conductors, and the leakage spurious mode wave is reflected by a spurious-mode reflection circuit disposed parallel to the transmission line. The distance between the transmission line and the spurious-mode reflection circuit is equivalent to the length in which a wave reflected by the spurious-mode reflection circuit is cancelled by the transmission line.
