Nonlinear delay line (NDL) technology has been utilized to implement a proof-of-principle, broadband, 8-channel, linear, hybrid NDL-based phased antenna array (PAA) system. The hybrid NDLs provide up to 267 ps analog, variable true time delay (TTD) with <5-dB measured insertion loss. A PAA system incorporating wide-band feed, transition, and antenna elements has been developed for broad-band (4-18 GHz), electronically controlled beam steering. The current system has demonstrated up to ±180 beam steering from 4 to 5 GHz, and ±6° at 6 GHz in good agreement with theoretical predictions; monolithic implementations have been designed to provide ±19° beam steering at frequencies up to 18 GHz and are currently being fabricated. This system provides a wide-band, low-cost, high-precision alternative to conventional PAA technologies
