Abstract :
Time delay units are needed in large, wideband arrays that scan to angles far from boresight. The time delay consists of many different sizes of transmission line lengths that incrementally increase the signal path length. This paper shows the trade-offs between cost and performance in the placement of the time delay in a corporate feed.
