ANTENNA APPARATUS OPERABLE IN DUALBANDS WITH SMALL SIZE

摘要

A radiator is provided with a looped radiation conductor, a capacitor, an inductor, and a feed point provided on the radiation conductor. The radiator is configured such that: a first portion of the radiator including the inductor and the capacitor and being along the loop of the radiation conductor resonates at a first frequency; and a second portion of the radiator including a section along the loop of the radiation conductor resonates at a second frequency higher than the first frequency, the section including the capacitor but not including the inductor, and the section extending between a feed point and the inductor.
