A Measurement of the Coupling Between Close-Packed Shielded Cassegrain Antennas

Page 836.

Abstract:

Design and performance details are given for a 0.9-m-diameter shielded cassegrain antenna, which will be used in a 13-element close-packed array. The array is designed to make images of brightness fluctuations in the cosmic microwave background radiation. Coupling between a pair of the shielded cassegrain antennas with a separation of 1 m is in the range -110 to -130 dB over the 26-to 36-GHz band.
