PROBLEM TO BE SOLVED: To provide an electromagnetic wave detector/generator having sensitivity in a plurality of different frequency bands, and the size of which can be made compact.SOLUTION: An electromagnetic wave detector/generator includes a plurality of antennas. The first antenna includes a first reception and radiation element 101, and a first electronic element 102 connected electrically with the first reception and radiation element, and has sensitivity for the first frequency band. A second antenna includes a second reception and radiation element 103, and a second electronic element 104 connected electrically with the second reception and radiation element, and has sensitivity for the second frequency band. At least some of the second reception and radiation elements are arranged on the inside of the first reception and radiation element. |
