NEC-LIST: phasing networks on collinear arrays

Hi, and thanks for reading this,

How does one model the inductive- looking section commonly used on a
cellular phone type antenna? It is my understanding that this
circuit element provides a current reversal to obtain in-phase
currents on adjacent half-wave sections of the antenna wire when
driven at one end against a ground plane. Without the 180 degree
phase shift, the half waves would be in phase opposition thereby
causing a multi-lobed pattern. A simple series inductance would not
seem to perform this function.

73 and thanks for any info,
