Abstract
Utilization of true-time-delay (TTD) is an important approach for improving the beam-pointing accuracy of wideband phased arrays. This paper studies the side lobe properties as the true-time-delay are equipped at subarray level. The study shows that side lobe levels increase because of periodic phase error. And then, an element-level TTD line scheme is proposed for effective reduction of side lobe levels.
