摘要:
A radiators has looped radiation conductors, an inductor, a capacitor, a feed point on the radiation conductor. The capacitor is formed by a capacitance between the radiation conductors, and the capacitance varies depending on positions on the radiation conductors within a portion where the radiation conductors are close to each other. The radiators is configured to: resonate along a portion of the radiator at a low-band resonance frequency, the portion including the inductor and the capacitor and being along the loop of the radiation conductor, and resonate along a portion of the radiator at a high-band resonance frequency, the portion including a section along the loop of the radiation conductor, the section including at least one of the at least one capacitor, not including the inductor, and extending between the feed point and the inductor.
