Abstract :
Applications of millimeter-wave radar, imaging and communication technology requires cost effective implementation of intelligent scanning antenna systems. This paper presents the design and measurement results of a new type nonlinear antenna array based on injection-locking theory. The required phase relation for each array element is obtained by electronic tuning through injection-locking technique, and the beam-scanning capability is demonstrated, so a shifterless beam scanning method is proposed, and an 1 X 4 element phase array verifies its feasibility.
