Measurements of a compact surface wave launcher array with application to single frequency beam steering leaky wave antennas

Abstract

Surface wave launchers have been used to feed leaky wave antennae. We present here for the first time measured results of a two element CPW-fed surface wave launcher array. It was shown at 22 GHz that this array can beam steer the surface wave 40deg. Array fabrication, measurement set-up and signal processing will also be described in the paper.
