Cavity Backed Spiral Antenna Model ASO-1665A, AA
Overview
This ASO-1665 Cavity-Backed Spiral Antenna exhibits frequency-independent free-space radiation patterns, low axial ratio, and isotropic gain levels. This circularly polarized antenna can be flush mounted behind a fairing or similar dielectric cover for airborne applications. Upon request, Honeywell can furnish flush radomes for single apertures or multiple apertures as necessary. The ASO-1665 provides semi-constant beam-widths in both planes over its entire operating bandwidth. In addition, the ASO-1665 antenna is available in phase and amplitude matched sets for use in Interferometer applications. Variants of the ASO-1665 are in service on a wide variety of platforms in precision DF and RWR applications.
