Kind Code:
A1
Abstract:
[Problem]
To provide an antenna-mounted communication IC unit which exhibits high communication performance when attached to a conductor, and an antenna-mounted communication IC unit equipped with a conductor.
[Solution]
Provided is an antenna-mounted communication IC chip 1 is equipped with at least an antenna unit 20 formed by stacking substrates 31 on which coils 32 are formed, and an IC chip 10 connected to the antenna unit, wherein the antenna unit is equipped with a main element 30 formed by connecting multiple coils in series such that the directions in which they generate magnetic flux coincide, and an auxiliary element comprising a coil 41 having an open section 42 and having less than one turn, and the main element and the auxiliary element are electromagnetically coupled. By connecting the main element and the auxiliary element such that the directions in which they generate magnetic flux coincide, the entire conductor 50 can be made to function as an antenna.
