Am trying to make a microstrip transmission line as a delay line. I was initially intrigued by a couple of papers touting delay lines with very short phyical length but long time delays over a broad bandwidth. One paper touts 2 nS of delay in a 60 mm length.
But when I take the papers and simulate them with Sonnet, I am getting nothing like the time delays the papers are quoting. I am only getting maybe twice what a standard 50 ohm transmission line would get, not the 10 x the time delay promised.
Anyone else try to design a delay line with left handed elements, and did you succeed? Either I am doing something very wrong, or these papers are wildly over optimistic in their predictions!
