Abstract
It is an object of the invention to provide a loop antenna constituted by a single element which can apply a magnetic field to carry out a communication reliably with high precision irrespective of the position and direction of a radio communication medium.
The invention provides a loop antenna 1 including a conductor 2, a plurality of bending portions 50 provided on the conductor 2, and a feeding portion for supplying a signal current to the conductor 2, the conductor being turned circumferentially like a loop by setting the feeding portion to be a base point, wherein the conductor 2 forms a three-dimensional space. Consequently, it is possible to generate a magnetic field to all dimensions, thereby carrying out a communication irrespective of the position and direction of a radio communication medium.
