This paper presents the preliminary design of a reconfigurable reflectarray using a direct optimisation approach, which has not been done before. The reflectarray employs a five-state configuration based on an aperture-coupled stacked patch element, offering phase quantisation within a 320…

A 1.4 m representative breadboard of the Copernicus Imaging Microwave Radiometer (CIMR) mesh reflector antenna was manufactured and its radiated field was measured using the planar near-field scanner of Thales Alenia Space Italy (TASI) in Rome. In this paper we…

The Arctic Weather Satellite is a single payload prototype for a meteorological constellation of SmallSats called EPS-Sterna. Previous analysis showed that the Arctic Weather Satellite radiometer suffers from significant spillover in the 54 GHz band. To accurately model the scattering…

The European Space Agency is currently working on realizing the Copernicus Imaging Microwave Radiometer (CIMR) which is a satellite-based multi-frequency microwave radiometer and one of the most ambitious missions of the Copernicus space segment. In this paper, results from the…

The Copernicus Microwave Imaging Radiometer (CIMR) employs a 7.1 m conical scanning mesh reflector antenna rotating at 7.8 rpm that operates from L to Ka band. Demanding radiometric accuracies and sensitivities at few tenths of a Kelvin at high spatial…
