Abstract
This letter presents a beam-steering antenna controlled by gravity. It provides a new beam-steering mechanism. The maximum radiation direction could be adjusted by assigning the center of gravity of the ground. The coaxial feed line and ground are separated, granting the ability for rotation between the two components. As the verification, based on the proposed structure, a prototype Yagi-Uda antenna working at 2.45GHz is manufactured and measured. The antenna realized 360° rotation, and the peak gain is 6.8dBi. Passive beam control could be achieved, and the variation of the gain in the desired direction is within 0.2dB during steering. The simulation results of the antenna prototype agree with the measured ones. This simple and practical structure provides a new solution for systems which demand adaptive antenna beam in certain directions.
