摘要

提出了一种工作频率为3.5 GHz ~ 5.5 GHz的宽带小型化可重构天线。该天线结构简单，采用1个锥形交叉辐射槽、4个寄生槽和8个PIN二极管。四个二极管控制四个反射槽来控制辐射方向图，其他二极管用来切换馈电路径来改变辐射光束的偏振。超表面作为反射器，减少后瓣，同时保持天线的轮廓小。给出了仿真结果。主瓣的最小增益为7dbi，可以在两个垂直的仰角平面上沿0°，±17°的5个位置操纵。

Design of Compact Beam-Steering Active Slot Antennas with a Metasurface Reflector

A wideband and miniaturized reconfigurable antenna operating from 3.5 GHz to 5.5 GHz is proposed. This antenna has a simple structure and uses one tapered crossshaped radiation slot with four parasitic slots and eight PIN diodes. Four diodes are used to control four reflector slots to steer the radiation pattern and the other diodes are used to switch the feeding path to modify the polarization of the radiated beam. The metasurface acts as a reflector and reduces the back lobe, while keeping the profile of the antenna small. Simulation results are presented. The main lobe has minimum gain of 7 dBi and can be steered along 5 positions 0°, ±17° in two perpendicular elevation planes.
