    Abstract

    Modeling of moderately thick wires can often involve feedpoint effects, which may or may not be handled properly when compared to actual physical construction and experimental measurements. In this paper, it is shown that attaching the two feedpoint wires on one side of a hollow cylindrical tube in the form of a dipole will introduce a frequency shift in the impedance or VSWR from what NEC4 would compute. A code such as WIPL, which uses a combination of plates and wires in an EFIE approach, is shown to produce results which are correlated well with experimental measurements of the physical dipole. Finally, this paper shows that a correction factor in length can be implemented to produce equivalence with NEC4 results even for bent stubs at the end of the dipole. This has implications in using codes such as NEC4 for optimization in arrays and construction of physical antenna elements.
