To provide an antenna etc. operated at a plurality of arbitrary frequencies and capable of individually controlling an operating frequency.SOLUTION: An antenna 10 includes: a GND plate 1 having an opening formed inside; a first split part 31 composed of two opposite conductors 311, 312 which are arranged inside the opening in a manner to face each other with a predetermined gap, and two connection conductors 313, 314 which connect each of the two opposite conductors to the outer periphery of the opening; a second split part 32 composed of two opposite conductors 321, 322 which are arranged inside the opening in a manner to face each other with a predetermined gap, and two connection conductors 323, 324 which connect each of the two opposite conductors to the outer periphery of the opening; and a power supply conductor 4 connected to one side of the opening. The antenna can be operated at a plurality of operating frequencies.SELECTED DRAWING: Figure 1 【課題】複数の任意の周波数で動作し、かつ動作周波数を個別に制御可能なアンテナ等を提供する。【解決手段】アンテナ１０は、内部に開口部が形成されたＧＮＤ板１と、開口部の内部に互いに対向するように所定の間隔を空けて配置した２つの対向導体３１１、３１２、及び当該２つの対向導体それぞれと前記開口部の外周を接続する２つの接続導体３１３、３１４で構成された第１のスプリット部３１と、開口部の内部に互いに対向するように所定の間隔を空けて配置した２つの対向導体３２１、３２２、及び当該２つの対向導体それぞれと前記開口部の外周を接続する２つの接続導体３２３、３２４で構成された第２のスプリット部３２と、開口部の一辺と接続される給電導体４と、を備え、複数の動作周波数で動作可能なことを特徴とする。【選択図】図１
