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…

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…

It is demonstrated that nonsingular  higher-order hierarchical Legendre  basis functions are capable of accounting for the singularities of the electric currents at the edges of the reflectarray elements, thus yielding good convergence properties and very accurate results. In addition, the…

Many exciting developments are underway at TICRA, as evidenced by recent and upcoming releases of new EM tools. One of the big news is the release of GRASP 10, which sets new standards for reflector antenna modeling in an efficient…
