Title:
HIGH-FREQUENCY TRANSFORMER, HIGH-FREQUENCY COMPONENT AND COMMUNICATION TERMINAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/188739
Kind Code:
A1
Abstract:
A first inductor and a second inductor are constituted from conductor patterns formed over a plurality of layers; conductor patterns (L1a,L1b,L1c,L1d) of the first inductor and conductor patterns (L2a,L2b,L2c) of the second inductor have respective coil-winding axes oriented in the layering direction and respective coil apertures disposed so as to be divided into two locations (coil apertures) of a first coil aperture (CA1) and a second coil aperture (CA2); the conductor patterns of the first inductor and the conductor patterns of the second inductor are respectively linked while alternating between the two locations of the first coil aperture (CA1) and the second coil aperture (CA2); and, in a state where a current is passed between a first input/output port (P1) and a third input/output port (P3), a magnetic flux generated in the first coil aperture by the first inductor and the second inductor forms a closed loop.
