Novel antenna architectures for real aperture multi-beam radiometers providing high resolution and high sensitivity for accurate sea surface temperature (SST) and ocean vector wind (OVW) measurements are investigated. On the basis of the radiometer requirements set for future SST/OVW missions,…

The 3D reconstruction algorithm of DIATOOL is applied to the BTS1940 antenna, recently measured at the DTU-ESA Spherical Near-Field Antenna Test Facility in Denmark. The antenna was measured mounted on the antenna tower through a custom support structure. The purpose…

The design and optimization of multi-faceted reflectarrays for satellite applications are presented. The objective of this work is to investigate the performance of a multi-faceted reflectarray designed using a direct optimization technique. To this end, a single-layer multi-faceted reflectarray, that…

The Multilevel Fast Multipole Method (MLFMM) allows for a reduced computational complexity when solving electromagnetic scattering problems. Combining this with the reduced number of unknowns provided by Higher-Order discretizations has proven to be a difficult task, with the general conclusion…

A generalized direct optimization technique (GDOT) for the design of printed reflectarrays using arbitrarily shaped elements with irregular orientation and position is presented. The GDOT is based on the spectral domain method of moments (SDMoM) assuming local periodicity (LP) and…
