<p>PROBLEM TO BE SOLVED: To provide a low profile antenna operable at a plurality of resonance frequencies.SOLUTION: An antenna device has a structure where cells, each consisting of a multilayer structure of a conductor and a dielectric. are arranged in matrix, and has a first antenna element and a second antenna element arranged on the structure. The cell has magnetic wall effect corresponding to different frequencies in the first direction and second direction, and the first antenna element and second antenna element are arranged, respectively, in a first direction and a second direction in parallel with the structure.</p> |
