Abstract
A branch-line hybrid-ring (BL hybrid) is composed of four quarter- wavelength transmission lines (TLs), and occupies large area on printed- circuit boards because of its loop structure, so that reduced-size hybrid- rings using multilayer meander-like TLs or lumped capacitors have been pro- posed 1,2 In this paper, a BL hybrid which uses coupled 'Us called a micro- wave C-type section (C-section)3'4, is proposed for the miniaturization.
