Scan impedance for an infinite dipole array: Accurate theoretical model compared to numerical software

A theoretical model of VanKoughnett and Yen fo ran infinite planar dipole array has been revised and extended to the case of a finiste 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 numberical simulation data.
