An efficient full-wave solver for the computation of monostatic Radar Cross Section (RCS) for electrically large structures using the method of moments is developed. This is accomplished by utilizing higher-order basis functions, to reduce the number of unknowns, and the…

The full-wave array decomposition method for regular antenna arrays with arbitrary elements using higher order hierarchical basis functions is investigated. We show that the use of higher-order basis functions results in significantly reduced memory consumption and computation time for a…

Excitation coefficients for a phased array feeding an offset reflector are optimized for use on a geostationary satellite. The design method is exemplified by optimizing beams for inflight internet over the Atlantic at two times during a day. All sets…

The performance of the Array Decomposition Method for finite regular antenna arrays with arbitrary identical elements using higher-order basis functions is investigated. We demonstrate how using higher-order basis functions results in significantly reduced simulation time for a 10 x 10…

A development project of a new software tool for uncertainty quantification (UQ) of an antenna’s performance caused by the stochastic behaviour of design variables of the system has been performed within the ESA Contract No. AO/1-10116/19/NL/AS. The mathematical algorithms implemented…
