    • An antenna comprises at least one half-slot antenna element 12 arranged in a recess, where the recess provides a ground plane wall 16 for the said at least one half-slot antenna element 12. The slot antenna element may be a half-Vivaldi antenna element. Also disclosed is an antenna which comprises at least one antenna element 12 arranged in a recess, where the recess provides a ground plane for the said at least one antenna element and the antenna element 12 comprises a conductive plate arranged perpendicular to the mouth 20 of the recess and is spaced from a wall 16 of the recess to provide a slot 14 between the edge 6 of the conductive plate and the wall 16 of the recess. Further disclosed is an antenna comprising a common ground plane and a plurality of antenna elements 12, where each antenna element comprises a conductive plate arranged perpendicular to the common ground plane and where the edge 6 of each antenna element plate is spaced from the ground plane to provide a slot 14 between the edge 6 of the conductive plate and the common ground plane. The recess may be a tapering polyhedral cone-like formation with linear and/or curved wall portions and a closed end 22 and open end 20 formed by a 3D-printer. The antenna may be used in telecommunication systems.

    • A mounting unit (210) securely mounts a radio wave reflection device (200) on a stable installation place such as a pole (20). A reflector unit (300) holds two reflectors (350, 360) at a tilt angle of 45°, allowing the two reflectors (350, 360) to be coaxial and rotatable independently of each other. A joint unit (220) connects the reflector unit (300) and the mounting unit (210). The joint unit (220) has rotational freedom along two axes (AZ axis and EL axis) orthogonal to each other. A radio wave reflecting device that relays, by reflection, radio communications between a first antenna device and a second antenna device distant from each other is thereby provided.
    • 安装单元(210)将无线电波反射装置(200)牢固地安装在诸如极(20)的稳定安装位置上。 反射器单元(300)以45°的倾斜角保持两个反射器(350,360),允许两个反射器(350,360)彼此独立地同轴和可旋转。 连接单元(220)连接反射器单元(300)和安装单元(210)。 接头单元(220)沿着彼此正交的两个轴线(AZ轴线和EL轴线)具有旋转自由度。 由此,提供了通过反射来中继第一天线装置与彼此远离的第二天线装置之间的无线电通信的无线电波反射装置。
