PROBLEM TO BE SOLVED: To provide a communication device and an antenna device that are capable of handling a plurality of bands and obtaining a sufficient antenna characteristic with the same size as a single SRR antenna unit.SOLUTION: A communication device includes: a split ring resonator antenna that includes a split ring unit, an impedance control unit and a power supply unit, and has a first resonant frequency; and an antenna element connected with the split ring resonator antenna via an LC parallel circuit or a first inductor. A second resonant frequency formed by the power supply unit, the LC parallel circuit or the first inductor, and the antenna element is different from the first resonant frequency. |
