The European Large Deployable Reflector (LDR) antenna underwent RF test in November 2020, becoming the first 5.1 m antenna in light mesh technology developed and measured in Europe. In this paper we present the correlation between the measured and predicted…

A dual-band (Tx/Rx) multiple spot beam reflector system for high throughput satellites in Ka-band is presented. The configuration is a multiple-feed-per-beam dual reflector Cassegrain antenna with a frequency selective surface (FSS) sub-reflector that separates the response between Tx and Rx…

Design and simulation results of a polarisation-selective reflectarray in Ka band are presented. The reflectarray is part of a dual-offset antenna system for a high-resolution and wide-swath Synthetic Aperture Radar (SAR) instrument that operates in both a high-resolution mode with…

We present the RF model and correlation with measurements in K band (18.7 GHz) of a 5.1 m diameter deployable reflector antenna in lightweight mesh technology. The RF model includes the manufactured surface shape, electrical properties of the lightweight mesh,…

In this paper, we present a computational model of the DTU-ESA Standard Validation antenna VAST12, and investigate the impact of how different features on the antenna impact the radiation pattern. It is shown that the termination of the central tube,…
