| Zusammenfassung: | To provide an antenna that is easy to fine-tune a resonance frequency and usable in a wide frequency band, and a radio communication system.SOLUTION: An antenna includes a first antenna element including a plurality of spherical conductors with an equal shape in the middle in a longitudinal direction of a linear conductor; and a second antenna element that is plane-symmetric with the first antenna element with, as a plane of symmetry, a virtual plane passing through a point on the extension of a longitudinal center line of the linear conductor near the outside of one end of the liner conductor of the first antenna element.SELECTED DRAWING: Figure 1
【課題】 共振周波数の微調整が容易で、広い周波数帯域で使用可能なアンテナ、および無線通信システムを実現する。【解決手段】 線状導体の長手方向の途中に複数の等しい形状の球状導体を有する第１のアンテナ素子と、前記第１のアンテナ素子の前記線状導体の一端の外側近傍で前記線状導体の前記長手方向の中心線の延長上の点を通る仮想的な平面を対称面として前記第１のアンテナ素子と面対称である第２のアンテナ素子とを備える。【選択図】 図１ |
