Abstract
Variable constant time delay adjustable by 20% over a bandwidth of 300 MHz at X-band has been theoretically obtained using a single delay line consisting of two ground planes. This has been achieved by rotating the direction of the applied DC magnetic field in the forward volume wave to the backward volume wave plane and adjusting the magnitude. Electronically variable constant delay lines have potential application in broadband phased array antennas and microwave signal processing.
