| Summary: | A study combining theoretical analysis and electrical performance testing of thin lens-reflector elements for use on a high-gain, directional, broad-band, passive communications satellite was conducted. It was determined that a diffraction-limited device, where the diameter was four wave lengths at the design frequency, was superior to a refracting lens-reflector having a diameter of 18 wave lengths at the design frequency, considering incident angles from 0 to 45 deg. As part of the program, the interrelation between element design and satellite characteristics were developed and several types of elements were compared. A 10in. - diameter plano-ellipsoidal lens and a spherical reflector were selected as an optimum design. A lightweight inflatable element of this design was tested. |
