An uncompromising dual frequency antenna for telemetry tracking applications
Abstract
A state-of-the-art, two-axis, automatic telemetry tracker is reported that represents the first use of the dichroic technique in this application and also performs beyond expectation. The frequency-selective surface is briefly discussed and the antenna system is described, including the S-band, X-band dichroic subreflector, X-band feed horn, and X-band circular polarizer. The key to the antenna system is the frequency-selective surface of the subreflector for the X-band Cassegrain antenna. The surface of the dichroic reflector appears solid and highly reflective to X-band energy while being transparent to the S band.
