    Solid-state retrodirective phased array concepts for microwave power transmission from Solar Power Satellite (1980)
    In:  Other Sources
    Details
    Publication Date: 2011-08-18
    Description: Two prototype solid-state phased array systems concepts for potential use in the Solar Power Satellite are described. In both concepts, the beam is centered on the rectenna by means of phase conjugation of a pilot signal emanating from the ground. Also discussed is on-going solid-state amplifier development.

    The Resonant Cavity Radiator (RCR) (1980)
    In:  Other Sources
    Details
    Publication Date: 2011-08-18
    Description: The fundamental theory of MW antenna operation and basic array technology development status was used in the design of the 1-km diameter 5-Gw SPS microwave antenna. However, the aperture size and the high efficiency requirements make the MW antenna extremely complex. Studies show that the slotted waveguide array is one of the most efficient radiators for the antenna. Subsequent analyses show that the temperature interface between waveguides and dc-RF conversion tubes can cause severe thermal design problems on the array. An alternate design, the Resonant Cavity Radiator, is described here.

    The Resonant Cavity Radiator (RCR) (1980)
    In:  CASI
    Details
    Publication Date: 2016-06-07
    Description: The design of the resonant cavity radiator (RCR) is compared to that of the slotted waveguide array in terms of efficiency, weight, and structural integrity. It is shown that the RCR design has three significant potentials over the slotted waveguide array: (1) improvement in efficiency; (2) lighter weight; and (3) simpler structure which allows the RCR to be integrated with the RF tube to alleviate thermal interface problems.
