Abstract :
Left-handed microstrip delay lines implemented by Complementary Split Ring Resonators (CSRRs) have been designed, fabricated and tested. The measured results reveal that the left-handed microstrip CSRRs can realize much longer delay in time as compared to conventional transmission lines for the same lengths. In this paper, for the length of 96 mm, a 12-cell CSRRs can provide the highest delay approximately 16 ns, whereas a conventional line can only offer the delay of only 6 ns with the length of 48 mm. The much needed delay properties with compact size of the lines will lead to their application in phase array radar systems.
