ANALYSIS OF THE TRANSITION BETWEEN TWO COPLANAR WAVEGUIDE TRANSMISSION LINES

摘要

Different approaches for the transition between two coplanar waveguides of different characteristic impedances have been investigated to improve the efficiency of both feeding network and the antenna element of an antenna system operating in the X-band. Return loss, effect of feed line shaping and parametric study are presented with each approach. The outcomes of this study leads to efficient transition between the antenna element and its feeding network.
