<p>The branch-line consists of two parallel main conductors on a dielectric substrate, and connecting lines between them at specified spacings. The two outer lines consists of at least three connecting lines in the form of a slot lines consisting of slots in metallisation on the substrate side opposite to the other conducting traces. They cross the main conductors at right angles in their end areas. The distance between the main conductors lines and the extensions of the conductor lines beyond the ends is a quarter-wave length or multiple thereof.</p> |
