Claim Text:
1. Microwave circuit in strip line technology, comprising: metallic resonator strips on one side of a dielectric layer, whereby alternately an opposite end of one of said consecutive resonator strips is connected through at least one via to a metallic surface on an opposite side of said dielectric layer, wherein said end of each resonator strip is formed relative to said at least one via so that an effective electrical length of each of said resonator strips connected through said via is identical for all resonator strips independent of an exact position of said via; wherein said end of each resonator strip is formed relative to a position of its corresponding via such that the end of each resonator strip is positioned in a same direction relative to its corresponding via; and wherein an end of each second consecutive resonator strip is loop-shaped and elongated so that an identical deviation of each via in relation to its corresponding resonator strip leads to an identical shift in the effective electrical length of each resonator strip in combination with its via for all directions of the deviation.
