介绍了一种轻量化小体积电子扫描天线的设计。该天线除了作为辐射孔径外，还可作为小型重量敏感遥控飞行器（RPV）的负载分担机身面板。组装了包含微带辐射元件、带状线馈电电路和微带线p-i-n二极管移相器的演示阵列，以评估该阵列的电气特性和扫描能力。演示阵列在天线范围上测试并且作为雷达/通信子系统演示的一部分成功操作。随后，利用数控机器和最先进的印刷电路板蚀刻和电镀设备，在现代化的生产设施中设计和制造了演示阵列的八元素轻质部分。该轻量化部分的成功运行充分证明了轻量化和低体积电子控制相控阵天线可以制造并集成到结构面板中进行量产。
A design of a lightweight low volume electronically scanned antenna is described. This antenna, besides being the radiating aperture, serves as a load-sharing fuselage panel in a small weight-sensitive remotely piloted vehicle (RPV). A demonstration array incorporating the microstrip radiating elements, stripline feed circuit, and microstrip-line p-i-n diode phase shifters was assembled to evaluate the electrical characteristics and scanning capabilities of the array. The demonstration array was tested on the antenna range and operated successfully as part of a radar/communication subsystem demonstration. An eight-element lightweight section of the demonstration array was subsequently designed and fabricated in a modern production facility utilizing numerically controlled machines and state-of-the-art printed circuit board etching and plating equipment. Successful operation of this lightweight section sufficiently demonstrated that a lightweight and low volume electronically steerable phase-array antenna can be fabricated and integrated into a structural panel in production quantities.
