Abstract :
This paper discusses the use of mutually EM transparent arrays mounted on EM transparent positioner arms. Three such arrays are mounted in a single radome and configured to independently track three separate signals. The three antennas are supported by pivots (azimuth) and dielectric yokes (elevation) so that all-sky coverage is possible without collisions. Frequency selective surface concepts are used in the design of the ground plane surface and the transmission lines to mitigate blockage effects.
