Add to ORKGIn this paper, we describe the near-field measurements of the surface of a 120 GHz reflectarray. The reconfigurable offset-fed reflectarray under development consist of approximately 3700 coplanar patch antenna elements which are individually controlled by 4-state micro-electro-mechanical (MEMS) phase shifters. Measurements of a static reflectarray preceding the MEMS-controlled one are done in order to characterize the behavior of individual antenna elements of the reflectarray. Measurement setup, probe selection and the effect of the directional coupler are described. Amplitude and phase patterns of the reflectarray are shown. Also the main characteristics of the static reflectarray under test are presented
