Abstract

A plurality of circular or elliptical first, second, and third strip conductors are formed on the surface of a substrate made of a dielectric single crystal. The first, second, and third strip conductors are coupled to one another via gap portions. A ground plane is formed on the entire rear surface of the substrate. A first coupling terminal and a second coupling terminal are inductively coupled to the first planar circuit resonator in directions where first and second coupling terminal excite the two resonant modes of the first planar circuit resonator, which are orthogonally polarized.
