Document Type and Number:
WIPO Patent Application WO/2015/107834
Kind Code:
A1
Abstract:
The objective of the invention is to provide an antenna component capable of obtaining a large output. The antenna component comprises a magnetic material core and a coil antenna that includes first to n-th coil parts wound around the magnetic material core (where n is an integer equal to or greater than three). The antenna component is characterized in that: the first to n-th coil parts are electrically connected in series with each other and arranged such that these parts are mutually separated and aligned in ascending order of first to n-th; and the number of turns of the second to (n − 1)-th coil parts is smaller than the number of turns of the first and n-th coil parts.
