Abstract: A planar phased array operating over 2-12 GHz with wide scan 60 degree off broadside and high-efficiency has been successfully designed and tested with a 16×16-element array prototype fabricated with low-cost standard commercial production processes. The measured performance is slightly better than that simulated based on the array factor and a moment-method solution for unit-cell in infinite array. The excellent and robust measured performance of the prototype sampled throughout its entire space-frequency domain is the first full-fledged demonstration of the viability of the planar phased array with multioctave bandwidth and wide-angle scan, which has been overshadowed by skepticism and controversies since its debut around 2000.
