摘要

In this article, a novel two-dimensional multi-beam antenna with a broad bandand a wide angle scanning range is proposed. It is composed a leaky-wavemetasurface (MTS) and a four-port feeding network with high isolation. Theleaky-wave MTS formed by T-shaped slots is displayed as radiator and dividedinto four angular sectors, each one devoted to the formation of a beam in agiven elevation plane. At every fixed frequency, the antenna can radiate multibeam in azimuth plane through exciting different ports. Also, multi-beam radiationwith a broad band and a wide angle scanning range in the elevationplane is realized when fixed port is excited at different frequency. The antennawith overall size of 207 mm by 207 mm by 2.0 mm is fabricated on FR-4 substrate.The measured and simulated results show that the 10 dB relativebandwidth is 30% (from 9.44 to 12.77 GHz). When different ports are excited atthe same frequency, the azimuth of radiation beam is steered to 0°, 90°, 180°,and 270°. In addition, the beam-scanning range of the prototyped antenna isfrom 29° to 75 when the frequency sweeps in the range of 9.5–12.0 GHz. Also,the maximum radiation efficiency reaches to 31.1% and the measured peakgain within the scanning range is 12.29 dBi.
