ABSTRACT:
A high-frequency circuit is formed on a multilayered dielectric substrate having at least two conductive circuit layers. The high-frequency circuit includes: a first spiral conductive strip formed in the first conductive circuit layer, the first spiral conductive strip having at least one turn; and a second spiral conductive strip formed in a second conductive circuit layer which is different from the first conductive circuit layer, the second spiral conductive strip having at least one turn and not being in electrical conduction with the first spiral conductive strip. The first spiral conductive strip and the second spiral conductive strip, located at different levels, overlap each other. The first spiral conductive strip has a rotating direction opposite to a rotating direction of the second spiral conductive strip.
