摘要

The paper uses a novel near-field phase transformation beam-steering method to steer the electromagnetic energy beam of compact resonant-cavity antennas (RCAs). The method is unconventional but versatile and can be used with a variety of low-to-medium gain antennas. The use of the method for a compact RCA validates its compatibility with low-gain antennas. The far-field results predicted by numerical simulations indicate that the antenna system can scan a beam having a peak directivity of 15 dBi into a conical region having an apex angle of 70°, without dropping peak directivity more than 3dB from the maximum value. This compact beam-steering antenna system is cheaper than active antenna arrays and convenient to operate than mechanically steered reflectors. The maximum height of the system is $1.3lambda_{0}$, which means that the antenna can be fixed inside a cylindrical cavity and its beam direction can be remotely controlled. Due to the low-cost and elegant design of the front-end antenna, a wireless backhaul mesh network can be established, which can be dynamically adjusted to improve quality of service.
