AN IMPROVED POINT-SOURCE COMPACT ANTENNA RANGE

Abstract

A point-source compact antenna range was modified by installing a range reflector having a more accurate surface contour and by shielding the reflector edge and its feed with absorbing material. Stray radiation measurements and pattern measurements were made within the band from 8.2 to 12.0 GHz using a 30-inch paraboloidal test antenna. Results are compared with those obtained on a previously constructed range, and they demonstrate that the range performance was improved. Measured maximum stray radiation levels on the modified range vary from about -44 db to about -58 db with respect to the collimated radiation. Radiation patterns compare very favorably with those measured on a 700-foot outdoor antenna range.
