摘要
Two different asymmetric branch-line hybrids, a conventional-direction asymmetric branch-line hybrid (CABH) and an anti-conventional-direction asymmetric branch-line hybrid (AABH) are discussed and their design equations are derived. On the basis of the derived design equations, a uniplanar CABH was fabricated with coplanar wave guide (CPW) technology and measured.
