Patent ID: 7132983

Claim:
A high-frequency signal transmitter with: a first strip line ( 10 ) on a surface of a dielectric substrate ( 11 ) for providing a signal; a second strip line ( 16 ) vertically spaced from the first strip line and located within the dielectric substrate ( 11 ) for the coupling-out and/or coupling-in of a high-frequency signal; a first interfacial connection device ( 15 ) in the substrate ( 11 ) for providing a vertical conductive connection between the first and second strip line ( 10 ; 16 ); a transition region ( 13 ), wherein in the transition region ( 13 ), the first strip line ( 10 ) transitions into a coplanar line ( 14 ) before the first interfacial connection ( 15 ); a first solid surface ( 12 ) essentially parallel to the first strip line ( 10 ) and serving as a lower boundary surface of the substrate ( 11 ) providing a shielding; a second solid surface ( 18 ) essentially parallel to the first solid surface ( 12 ) and disposed at least in the region above the second strip line ( 16 ) on the surface of the substrate ( 11 ) for providing a shielding; a coupling opening ( 17 ) in the second solid surface ( 18 ) for radiating high-frequency energy; a planar coupling device ( 19 ) above and essentially parallel to the coupling opening ( 17 ); and a second interfacial connection device ( 20 ) between the first solid surface ( 12 ) and the second solid surface ( 18 ), in the region adjacent to the transition region ( 13 ).
