Abstract

See full text

An antenna device includes a first radiating element, a second radiating element having lower radiation efficiency than the first radiating element, a coupling element including first and second coils that are electromagnetically coupled to each other, and first and second phase adjusting elements. The first and second phase adjusting elements induce, at a resonant frequency of the second radiating element, a predetermined proportion of current flowing through the second radiating element to the first radiating element.
