Coplanar differential bi-strip delay line, higher-order differential filter and filtering antenna furnished with such a line

摘要

This coplanar differential bi-strip delay line includes two conducting strips disposed on one and the same face of a dielectric substrate and each comprising a first and a second end. The two first ends of the two conducting strips are respectively joined to two conductors of a first bi-strip port for connection to a first external differential device. The two second ends of the two conducting strips are respectively joined to two conductors of a second bi-strip port for connection to a second external differential device.
