Abstract
A method for excitation of an array antenna across a specified bandwidth is disclosed. The specified bandwidth comprises M sample points, M being a positive integer >1, and the array antenna comprises N antenna elements, N being a positive integer ≥2. The method comprises forming a first matrix B(ω) defining an allowed frequency variation for an excitation coefficient for each antenna element, and forming a second matrix defining far field data for each antenna element at each sample point. Further the method comprises optimizing each excitation coefficient based on the formed first matrix and the formed second matrix, and controlling an excitation of the N antenna elements based on the optimized excitation coefficients. Hereby presenting a method for wideband optimization of the excitation coefficients for an array antenna.
