Slow-wave structure for miniaturized six-port junction

In this paper, we propose a miniaturized six-port junction composed of three hybrid couplers and a Wilkinson power divider based on slow-wave structures. High performances have been achieved in the frequency range from 300 to 500 MHz. The results of both electrical and electromagnetic simulations revealed a very good agreement between the conventional structure and the proposed compacted one that presents a reduction rate up to 66 %.
