摘　　要：本文提出了一种混和集成型有源阵列天线结构，并对这一结构进行了空间功率合成的实验研究。功率源采用微带型振荡电路；天线采用矩形微带贴片阵列，二者通过背馈相连。贴片天线阵间的互耦使振荡单元间实现注入镇定，各单元的辐射功率在空间实现合成。在Ｘ波段成功地实现了四单元有源阵列的互锁和空间功率合成。A new type of microstrip active antennas is investigated experimentally. The antennas considered here are rectangular microstrip patch arrays with integrated Gunn osicillators connected to the back of microstrip patch elements through apertures. Injection locking of antenna elements has been achieved through space and mutual coupling. The power output from the four elements has been successfully combined in free space. The experimental results at X- band and some significant conclusions are given.
