PROBLEM TO BE SOLVED: To provide a lens antenna device capable of suppressing increase in opening diameter of a reception antenna in a case where an OAM mode whose absolute value is equal to or more than one is used.SOLUTION: A reflection plate comprises a first reflection plate that has a structure of a rotation body obtained by making a range at least including a radiation position with a maximum gain for each OAM mode make one revolution around a radiation axis of an electromagnetic wave radiated from a transmission antenna, in an oblique ellipse that uses a center of the transmission antenna and one end of a reception antenna as focal points.SELECTED DRAWING: Figure 1 【課題】絶対値が１以上のＯＡＭモードを用いる場合に、受信アンテナの開口径の増大を抑制可能なレンズアンテナ装置を提供する。【解決手段】送信アンテナの中心と、受信アンテナの片端とを焦点とする斜め楕円において、少なくともＯＡＭモード毎の最大利得となる放射箇所を含む範囲を、前記送信アンテナから放射される電磁波の放射軸を中心として一回転してできる回転体の構造を備える第１の反射板を備える。【選択図】図１
