ABSTRACT:
An assembly of antenna elements is mounted in a unitary structure for transport on a satellite encircling the earth. Each element comprises a horn shaped radiator with opposed arcuate sidewalls, a rectangular waveguide feed, and a transition interconnecting the feed to a throat of the horn. The assembly services a plurality of portions of a communication band within the electromagnetic spectrum. The throats of respective horns are dimensioned for specific frequencies of the respective portions of the communication bands. The antenna elements may provide telemetry and control functions for the satellite. A side-by-side arrangement of the horns permits use of a common meanderline polarizer for conversion of a linearly polarized wave to a circularly polarized wave for each antenna element.
