Abstract

A recently proposed antenna measurement technique based on impedance or reflection coefficient measurements with varying reflective objects in front of an antenna is reviewed. The method allows radiation pattern determination without moving cables which are subject to changes in their electrical length and attenuation during conventional antenna measurements. In addition, a modification to the method is introduced in order to speed up the involved iterative optimization process.
