Abstract

The indirect two-port reflection method for measuring antenna impedances is reviewed using scattering parameter techniques and developed into a more accurate low perturbation optically coupled transmission measurement. This transmission measurement infers the antenna impedance by measuring the voltage induced in a number of loads connected to the antenna port with reference to the antenna used for illumination. Both these techniques have proved to be very versatile: applications to a typically electromagnetic compatibility problem, consisting of a box and wire above a ground plane, and
to the design of a challenging multi-band Digital Audio Broadcast antenna are presented.
