摘要

本文设计了一种可重构全息天线，该天线采用带有480个预装槽的SIW波导，由串行波导馈电。PIN二极管安装在插槽中，以便根据全息干涉图案控制插槽的工作状态。仿真结果表明，在26.5 ~ 28.5 GHz频段，全息天线可在仰角方向-45°~ 45°范围内进行扫描;最大增益为11.4~14.1dBi。仿真结果表明，所设计的天线在5G系统中具有良好的波束形成性能。

Digital encoding holographic antenna based on SIW waveguide

This paper designs a reconfigurable holographic antenna, using the SIW waveguide with 480 preinstalled slots fed by a serial-fed waveguide. The PIN diodes are installed in the slots in order to control the working states of the slots according to the holographic interference pattern. It can be obtained from the simulation results that the holographic antenna can be used to scan from -45° to 45° in the elevation direction over the band 26.5 to 28.5 GHz; the maximum gain is 11.4~14.1dBi. As shown by the simulation result, the designed antenna puts up a good performancein beamforming for the 5G system.
