Abstract
Theoretical wire grid modelling for antennas on structures involves the approximate solution of an approximate problem. By experimentally modelling the approximate problem of a wire grid replacing a continuous metal structure, it is shown that a wire grid with spacing ¿ ¿/10 is a good approximation both for the far-field radiation pattern of the antenna and for its input impedance. Difficulties in providing accurate impedance predictions should therefore be ascribed to the approximate mathematical solution, rather than the wire grid model.
