摘要

本文提出了一种基于半模基片集成波导(HMSIW)技术设计低轮廓腔背模式可重构天线的有效方法。由插入式微带馈线馈送的HMSIW腔激发一个矩形贴片。通过电子控制HMSIW和一对贴片之间的几个PIN二极管的状态来实现不同的辐射方向。否则，通过开关PIN二极管的开/关状态，该槽可以作为辐射元件或光栅反射器工作。所提出的天线采用印刷电路板(PCB)工艺在自由空间波长为0.021的低轮廓的单层基板上制作。它还具有结构简单、高增益和低交叉极化电平等吸引人的特点。

Pattern-Reconfigurable Half-Mode Substrate-Integrated Waveguide Antenna

In this paper, an effective method of designing low-profile cavity-backed pattern-reconfigurable antenna based on half-mode substrate-integrated waveguide (HMSIW) technique is proposed. The HMSIW cavity fed by an inset $50\ \Omega$ microstrip feedline excite a rectangular patch. Different radiation direction are realized by electronically controlling the states of several PIN diodes between HMSIW and a pair of patches. Otherwise, by switching the on/off-state of the PIN diodes, the slot can operate as a radiating element or a grating reflector. The proposed antenna is made on a single-layer substrate with a low profile of 0.021 free-space wavelength using printed circuit board (PCB) process. It also perform attractive features such as simple structure, high gain and low cross polarization level.
