Abstract
This paper presents a new and simple approach for the Ka-band vernier pointing of a 34 m beam-waveguide (BWG) antenna (also applicable to a 70 m antenna). In this study, rotation of a BWG flat mirror, located at the elevation axis, is used to scan the beam instead of using the very large tipping structure of the antenna. The rotation of a BWG flat minor at another location is also investigated. The advantages of scanning the drastically smaller mirror with a less precise mechanism will be discussed. RF performance predictions will be presented.<>
