PROBLEM TO BE SOLVED: To provide an antenna device having no limitation in the combination of a plurality of frequency bands of electromagnetic waves for use, if a plurality of reflection boards and an antenna element are disposed at positions having an identical ratio to the ratio of the plurality of frequency bands of the electromagnetic waves for use.SOLUTION: An antenna element 110 communicates with electromagnetic waves of a plurality of frequency bands. A plurality of frequency selection boards 121, 122 respectively function as frequency filters for at least one radio wave among the plurality of frequency bands. A plate disposition member disposes the antenna element 110 and the plurality of frequency selection boards 121, 122 successively in a radio wave direction. |
