ANTENNA DEVICE, AND WIRELESS COMMUNICATION DEVICE

摘要

A radiator (100) is provided with radiation conductors (1, 2) forming a loop, a capacitor (C1), an inductor (L1), and a feeding point (P1) disposed on radiation conductor (1). The radiator (100) is configured such that: a first section containing the inductor (L1) and the capacitor (C1) and along the loop of the radiation conductors resonates at a lower resonance frequency (f1); and a second section which is a section containing the capacitor (C1) but not containing the inductor (L1) in a section along the loop of the radiation conductors and which contains a section extending between the feeding point (P1) and the inductor (L1) resonates at a higher resonance frequency (f2).
