PROBLEM TO BE SOLVED: To provide a plurality of antennas close to each other in an antenna apparatus provided with a plurality of antennas arranged so as to transmit and receive mutually orthogonal polarized waves, and to deteriorate characteristics due to interference between antennas. To be able to suppress. An antenna device 2 includes a separator 23, solid electrolyte layers 24a and 24b formed on both sides of the separator 23, and wires made of a conductive polymer formed on the solid electrolyte layers 24a and 24b, respectively. Antennas 22a and 22b. When a DC voltage is applied between the antenna patterns 22a and 22b, one of the antenna patterns 22a and 22b can be doped with ions, and the other can be dedoped. That is, one of the antenna patterns 22a and 22b can be a conductor and the other can be an insulator. [Selection] Figure 5 |
