Abstract
A thin-film coupler with a carrier substrate ( ) and two strip lines disposed thereon, of which one represents the main coupler loop ( ) and one the auxiliary coupler loop ( ). The use of inexpensive carrier substrate materials and a compact construction are made possible through an integration of a strip line, a coil, or an LC combination into the auxiliary coupler loop ( ). The integration of these components ( ) achieves a phase shift in the frequency of the signal coupled out so that a broadband coupler is obtained which exhibits an identical coupling at at least two frequencies.
