Abstract

An effective transmission line coupling network for spatial power combining and beam scanning purposes is reported. The harmful effect of radiative coupling is eliminated using a modified version of this network for peripheral elements. A technique to control the inter-element phase differences of planar arrays was also developed. Experiments on 1/spl times/4 and 2/spl times/2 oscillator arrays using the proposed coupling network agrees well with the theory.
