Abstract:
1. An antenna, comprising: a power-feeding radiation electrode having a power feeding end and an open end, said power-feeding electrode configured to perform antenna operation in a basic mode in which resonant operation is performed in a basic frequency and antenna operation in a high-order mode in which resonant operation is performed in a frequency higher than the basic frequency; a non-power-feeding radiation electrode electromagnetically connected to the power-feeding radiation electrode, said non-power-feeding radiation electrode having one terminal serving as a ground-side end and another terminal serving as an open end; a bendable, flexible substrate on which is provided the power feeding radiation electrode and the non-power-feeding electrode with a gap therebetween; and a dielectric body having permittivity higher than that of the bendable, flexible substrate selectively provided on a front surface or a back surface of the power-feeding radiation electrode in a region near the power-feeding end and 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, wherein the power-feeding radiation electrode includes a loop path configured such that the power-feeding radiation electrode first extends in a direction away from the power-feeding end and the open end is bent toward the power-feeding end.
