A baffle has the purpose of preventing the feed of a compact antenna test range to radiate in the quiet zone and it is typically constituted by a cylindrical structure covered by pyramidal absorbers. In this paper we describe the...

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...

This work details the results of a so-called uncertainty quantification analysis conducted on the SKALA 4.2 log-periodic antenna, itself the intended production model of the antenna element for the SKA-Low Antenna Array. The antenna is modelled using the high-order Method...

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...
