An accurate and efficient tool for the design of contoured beam reflectarrays is presented. It is based on the Spectral Domain Method of Moments, the Local Periodicity approach, and a minimax optimization algorithm. Contrary to the conventional phase-only optimization techniques,...

In this paper, an electrical performance verification methodology is proposed for the large deployable reflector antenna of the BIOMASS P-band (435 MHz) synthetic aperture radar (SAR). The proposed methodology is based on measurement of the feed characteristics, such as complex...

We present a new efficient design tool for rotationally symmetric reflector antennas, possibly including 3D support structures and waveguide components. The tool is based on a combination of four solvers: Mode-Matching (MM) for cylindrical wave-guiding structures, a newly developed higher-order...

The 3D reconstruction algorithm is applied to a slotted waveguide array measured at the DTU-ESA Spherical Near-Field Antenna Test Facility. One slot of the array is covered by conductive tape and an error is present in the array excitation. Results...
