Abstract
The antenna device Aincludes an antennaconfigured to transmit and/or receive radio waves, and a dielectric elastomer drive elementincluding a dielectric elastomer layerand a pair of electrode layerssandwiching the dielectric elastomer layer. The dielectric elastomer drive element is capable of changing an antenna characteristic of the antenna. With such a configuration, the antenna device can be made smaller and lighter while improving its antenna characteristics.
