Many superconducting delay line structures have been implemented, using various technologies. In this paper, a comprehensive overview of these delay-lines is given. The advantages and disadvantages of using different planar technologies for the construction of superconducting delay lines are discussed in greater detail. It was revealed that most of the superconducting delay line structures reported can be categorized into a few popular structures, namely meander line, double-spiral line, and unit-cell structures. Our recently published novel double-spiral meander delay line structure is also included for comparison. The new structure was implemented using both microstrip and coplanar technologies and the performance is superior compared to any delay lines reported previously. Besides, investigated meander and fractal delay line structures were also reported, with theoretical analysis in frequency and time domains.
