Abstract
Array simulators based on cable delays plays an important role in array antenna testing and research. However, electromagnetic waves propagate at a relatively lower velocity in transmission lines than that in air, which results in some problems in design of array simulators. In this paper, the velocity difference is studied deeply, which has been employed in an array simulator with good angle resolution based on cable delays. A method of extending simulated angle range in beamforming by adjusting element spacing was proposed and studied, which provided a way for fully utilization of delay lines.
