Fig. 4From: Better than Rician: modelling millimetre wave channels as two-wave with diffuse powerPhotograph of the mechanical set-up for MC1 from the receiver point of view. The receive antenna, a conical 20 dBi horn, is mounted on a multi-axis positioning and rotating system. The azimuthal and elevation angle are controlled to scan the whole upper hemisphere. The multi-axis system moves and rotates the horn antenna such that its phase centre stays at the same (x,y) coordinate during the directional scanBack to article page
