Abstract :
The design, construction and performance of proof-of-principle true time delay phased antenna arrays (PAAs) based on both hybrid and monolithic nonlinear delay line technology are presented. A 2-D, 4×4 hybrid PAA exhibited approximately ±9° beam scanning in both the E-plane and H-plane at 5 GHz center frequency in agreement with theoretical predictions. A monolithic NDL-based PAA intended for operation at 6-18 GHz is currently under development and test. A longer term electronically controlled "lens" application for plasma reflectometric diagnostics requires a 1×8 array operating at 88 GHz.
