Large reflector antennas for telecommunication or space observation purposes often require a lengthy and detailed design process, where the design is carefully revised to ensure the best performance for the intended application. For many modern reflector antennas, quantification of the…

In many space applications, single offset reflectors operating in orthogonal circular polarization in Tx/Rx are required. For these applications, beam congruence in Tx/Rx is desired to ensure optimal performance over the service area. Several factors contribute to beam incongruence, e.g.,…

A next generation spaceborne radiometer system for hi-quality ocean measurements is discussed. Instead of a classical horn, a focal plane array is used as antenna feed. The antenna beam is created by adding the outputs from many small antenna elements,…

The present-day ocean remote sensing instruments that operate at low microwave frequencies are limited in spatial resolution and do not allow for monitoring of the coastal waters. This is due to the difficulties of employing a large reflector antenna on…

This paper presents the latest status of the full-wave simulation of MetOp-SG Ice Cloud Imager (ICI) and the methodology proposed to correlate both simulation and antenna pattern testing in two cases, namely for the main beam and the full 4π….
