A novel means of achieving cophasal far-field radiation has been demonstrated for a curcularly polarized microstrip reflectarray with elements having variable rotation angles. Two Ka-band, half meter microstrip reflectarrays have been fabricated and tested.

We consider a five blade rotor and envision an array with one element mounted on each rotor blade. These elements may be dipoles or horizontal slots depending upon the desired polarization characteristics. For example, slots would provide vertical polarization on horizontal paths. The array is excited through a novel type of rotary joint located on the rotor shaft.
