摘　　要：研制了一种反馈振荡型有源天线。其中微带贴片天线既作为辐射单元，又作为有源电路的反馈回路，同时满足振荡起振条件及天线辐射要求。通过测量辐射功率和方向图，表明该天线工作良好。天线工作频率为６．５４５ＧＨｚ，全向等效辐射功率（ＥＩＲＰ）为４５４ｍ Ｗ。The development of a feed back oscillating act ive integrated antenna is described in this paper.The microstrip patch antenna i s not only used as the radiating element,but also serves as the feed back circu it of the oscillator,so the oscillation and radiation can be obtained simultane ously.The radiating power and the patterns are measured,which proves that this t ype of active antenna works well.The operating frequency is 6.545GHz and the equ ivalent isotropic radiated power(EIRP) is 454mW.
