Highly miniaturised Wilkinson power divider employing π-type multiple coupled microstrip line structure

Abstract

Using a π-type multiple coupled microstrip line structure, a highly miniaturised Wilkinson power divider is fabricated. The line length of the power divider was reduced to about λ/44, and its size was 37% of a conventional Wilkinson power divider. The novel power divider showed good RF performances in S/C band.
