Abstract
An antenna coupling element includes a first coil connected to a first radiating element and a feeder circuit and a second coil connected to a second radiating element and electromagnetically coupled to the first coil. The first and second coils have a relationship in which a direction of a magnetic field generated in the first coil when a current flows from the first coil toward the first radiating element and a direction of a magnetic field generated in the second coil when a current flows from the second coil toward the second radiating element are opposite to each other. The first and second coils are set such that a resonant frequency of a fundamental wave of the second radiating element with a transformer defined by the first coil and the second coil is lower than a resonant frequency of a fundamental wave of the first radiating element.
