Abstract :
A review of full-wave and reduced-order modelling techniques for large, dense antenna arrays as proposed for the Square Kilometre Array is presented. A reduced-order method of modelling microstrip-fed Vivaldi Arrays, the Infinite Array Approximation as well as the Domain Green´s Function method are discussed with specific reference made to runtime, memory usage and solution accuracy as compared to that of brute-force MoM solutions.
