Abstract
The antenna includes a power-feeding radiation electrode and a non-power-feeding radiation electrode are provided adjacent to each other with a gap therebetween on the flexible substrate, which also is bendable. The power-feeding radiation electrode is used to perform antenna operation in a basic mode in which resonant operation is performed at a basic frequency and antenna operation in a high-order mode in which resonant operation is performed at a frequency higher than the basic frequency. The power-feeding radiation electrode includes a loop path configured such that the power-feeding radiation electrode first extends in a direction away from a power-feeding end and an open end is bent toward the power-feeding end. The non-power-feeding radiation electrode has one end serving as a ground-side end and the other end serving as an open end. A dielectric body having permittivity higher than the bendable, flexible substrate is provided on a front surface or a back surface of the power-feeding radiation electrode provided in a region including a portion in which voltage of a resonant frequency in the high-order mode is zero potential and a region in the vicinity of that portion.
