| 摘 要： | 介绍了一种在传统方形切角微带元上加PBG结构的微带天线。在辐射元的四周刻蚀了等间距的方型贴片,并在中心过孔与地板短路,形成高阻抗表面(HIGP)。仿真和实测结果表明,通过在方形切角微带元四周加高阻抗表面(HIGP)结构,能使天线在不改变园极化特性的基础上,有效地改善天线的前后比,提高天线的增益并有效减少天线的尺寸。

| Abstract: | A new PBG structure for the square patch with truncated corners microstrip antenna is presented.The probe-fed patch is surrounded by some etched square patches which are shorted to the ground.Simulation and experimental results show that this HIGP structure can improve the front to back ratio and the gain,meanwhile the circularly polarization performance is maintained. |
