Design of an axially displaced ellipsoid reflector antenna for a 4.6m diameter ship-borne transportable terminal at S-band

This paper presents a detailed study for realization of an optimized configuration of a 4.6 m diameter reflector antenna for ship-borne transportable terminal using axially displaced ellipsoid (ADE) configuration. Maximum gain achievable from the aperture coupled with system level parameters like G/T, accommodation of a feed capable of simultaneous uplink and downlink involving monopulse tracking and ease of assembly on a moving and constrained workplace like ship or a truck is also major driving parameter in the design. These parameters are explicitly analyzed and discussed in this paper.
