Abstract :
A theoretical model of VanKoughnett and Yen to ran infinite planar dipole array has been revised and extended to the case of a finite feeding gap with finite dipole spacing. the model was than compared with results from the Ansoft HFSS v.11 and CST Microwave Studio 2008 numerical antenna array simulators. The agreement among three approaches for the infinite dipole array was generally very good in all scan planes, with the exception of minor differences that can be accounted for. This confirmed both the new analytical model and the numerical simulation data.
