Övergång mellan stripline och mikrostrip i kavitet i flerlagers mönsterkort

摘要

The present invention relates to a multilayer printed circuit board arrangement which results in better matching between a stripline (9) and a microstrip (4) in a cavity (6). The solution comprises the use of an asymmetric stripline (9) where the electric field is tied primarily to the lower earth plane (10). This results in good matching at the transition to the microstrip (4), whose field is tied to the lower earth plane (10).
