In this article, the authors present results of focal field analyses carried out for front-fed and offset parabolic antennas for hybrid antenna configurations with arrays in the focal zone and provide insight from another point of view for antenna operations in the generic sense.Abstract:
In this paper, we present results of focal field analyses carried out for front-fed and offset parabolic antennas. Such analyses are needed and especially important for hybrid antenna configurations with arrays in the focal zone. The front-fed configuration relates to work carried out for radio telescope applications within the FARADAY project. The offset geometry relates to potential applications for instance for Earth observation or telecommunication satellites. The focal field analysis is necessary as an intermediate step, before focal field matching procedures are applied, to derive suitable excitations for a focal array. But also such an analysis gives insight from another point of view for antenna operations in the generic sense.read more

Point-to-point radio link variation at E-band and its effect on antenna design
TL;DR: In this paper, a focal plane array (FPA) was used as feed for the parabolic reflector antenna to tackle the mast movement by electronic beam steering and to increase EIRP by increasing the number of active antenna elements, and to assist the mechanical alignment during installation.
