摘　　要：研制中心频率为18 GHz的振荡型有源集成天线,包括微带天线设计、单片压控振荡器(MMIC VCO)的设计及微带天线与单片压控振荡器二者的集成。微带天线的芯片面积为4.5 mm×3.5 mm,增益为3.67 dB,中心频率为18.032 GHz,最小输入驻波系数为1.098;单片压控振荡器芯片面积1.1 mm×1.0 mm,调谐范围为15.978～18.247 GHz,输出功率大于6 dBm。振荡型有源集成天线的方向图测试结果与微带天线的特性符合,该振荡型有源集成天线能够正常工作。Oscillating mode active integrated antenna with center frequency of 18 GHz is designed and manufactured on GaAs. The work includes the design of microstrip antenna, MMIC VCO, and integrating of microstrip antenna and MMIC VCO. The chip area of microstrip antenna is 4.5 mm×3.5 mm, and the center frequency measured of microstrip antenna is 18. 032 GHz at againof 3.67 dB, and input VSWR of 1.098. The chip area of MMICVCOis 1.1 mm×1.0 mm, and the tuning range of MMIC VCO in 15. 978-18. 247 GHz, with output power of more than 6 dBm. The radiation pattern of oscillating mode active integrated antenna which can work successfully agrees with the character of the microstrip antenna.
