摘　　要：提出了一种新的结构功能一体化相控阵天线的高密度集成设计方法。采用低温共烧陶瓷(LTCC)技术实现了有源相控阵天线的一体化设计,包括天线阵面、瓦式收发(TR)组件、热控装置、馈电网络的高密度集成。采用ANSYS等软件对天线的系统体系构架、总体性能评估、共形承载天线罩、天线阵面、瓦式TR组件以及系统热设计进行仿真分析并进行实物加工和测试。结果表明,该天线的等效全向辐射功率(EIRP)为23.6 dBw,噪声为3.57 dB,测试值与设计值吻合很好。The novel high density integrated design method of the incorporate phased array antenna combining with structure and function Was proposed. The incorporate phased array antenna, including antenna array, tile transmitting and receving （TR） module, terminal control device, and feeding network, was realized by using low temperature co-fired ceramics （LTCC） technique. And then, the designs of system structure, collectivity capability evaluation, conformal load-bearing radome, antenna array, and heat design were simulated and analyzed by using softerware such as ANSYS and so on. Finally, the prototype was manufactured and measured. The results show that EIRP of 23.6 dBw and noise of 3.57 dB of the antenna are obtained. All the measured data match well with the simulation.
