NOVEL REFLECTARRAY ELEMENT WITH VARIABLE PHASE CHARACTERISTICS

The paper describes a novel dipole reflectarray element with variable reflection phase. The element is described and array waveguide simulat or measurement data demonstrating its phase shifting properties is pre sented, The element was developed originally as a mechanism for antenn a pattern tuning of a fixed-beam crossed-dipole reflectarray. However, it might also be applied, using small electric motors, to achieve ele ctronic scanning or active beam reshaping. These potential application s are discussed briefly.
