Parallel strip waveguide coupling for loop antenna

摘要

The coupling includes a structured, copper coated, flexible, dielectric carrier. On one side of a low loss dielectric carrier (1) of definite susceptibility, preferably a dielectric film, a planar structure is formed. This includes an arrangement of two parallel conductive, thin expandable layers (2) of given geometric dimensions. The parallel conductive surfaces are structured on a common surface of the dielectric carrier (1), with a homogenous and definite distance from each other. The parallel conductive surfaces (2) are galvanically coupled on the antenna side, with the exciting loop (3) of the loop antenna. One of the conductive surfaces (2.1,2.2) is coupled on the opposite side of the antenna with the earthed surface of the asymmetrical input/output of the coupled entry or exit apertures. The other conductive surface (2.2,2.1) is galvanically coupled to the conductor system of the input/output.
