ELECTRICAL COMPONENT AND ANTENNA
Document Type and Number:
WIPO Patent Application WO/2014/073395
Kind Code:
A1
Abstract:
This electrical component is equipped with a first coil and a second coil that is provided so as to surround the first coil. The first coil and the second coil are electrically insulated from each other. By connecting the electrical component to an antenna component, the antenna component can be made to resonate in two frequency bands. In addition, the first coil is provided on the inner side of the second coil. In addition, main parts of electrical components such as a transmission line and a band-pass filter can be constructed with the coils alone. The antenna can be made small and multiband-capable, and the electrical component can be manufactured highly robust and with high accuracy.
