| 摘 要： | 微带有源天线的应用具有降低通信系统的复杂度、减小系统尺寸的优点，但由于天线与有源器件集成在一起，有源器件产生的谐波可以引起天线的伪辐射。该文研究了PBG(Photonic Band-Gap)结构在有源天线中的应用。计算和实验结果都表明PBG结构的应用可以大大降低谐波引起的辐射，从而改善了系统的性能。

| Abstract: | In communication systems, the application of microstrip active antenna is useful for the simplification and downsizing of the system. But because the antenna is integrated with active devices, the harmonics produced by the active devices can result in the spurious radiation of the antenna. In this paper, the application of PBG(Photonic Band-Gap) structure to the active antenna is studied, and the calculated result and experimental result all indicate that the application of PEG structure can drastically diminish the radiation of harmonics, so the performance of system is improved. |
