We consider the static behavior and maximum critical current I m a x (H) for a given magnetic field H of a system of two point Josephson junctions separated by a distance 2a embedded in a rectangular microstrip of width w and show that the problem can be mapped onto an effective 1D situation with a rescaled width w<w which depends on the geometrical parameters a, w and mis-alignment b of the junction pair. The analysis of the reduced equations reveals that I m a x is periodic of period πa and yields the amplitude of its variation with the magnetic field H. In particular it is proportional to aw when a<w and is reduced when the mis-alignment b is increased. Since the geometric parameters can be freely chosen in the fabrication process we suggest that experimentalists can design a device to suit specific needs.
