2-Dimensional Nonlinear Delay Line-Based Phased Antenna Arrays

摘要

The design of a 2-dimensional phased antenna array based on hybrid nonlinear delay line (NDL) technology is presented together with a description of the test setup. A ture time delay controlled, 4x4 phased antenna array with a beam scanning angle of approximately +-10deg at 5 GHz center frequency is currently under development. An initial proof-of-principle demonstration of this concept was implemented successfully in a 1x8 1-D arrayby Hsia in 1998 (1). The newly designed array provides fully 2-dimensional beam steering capability, leading to a simple, compact and reliable system.
