The OFP and OFD can not only improve the wide-angle scanning ability of the antenna, but also increase the engineering feasibility of the SFOC antenna system.

二者的确定不仅改善了SFOC天线系统的扫描特性 ，而且提高了它的工程可实现性。

The structure of the SFOC antenna is constructed, and the optimum-feed position (OFP) and the optimum-feed direction (OFD) are analyzed by using the ray tracing method and the optimization method.

给出了SFOC天线的结构形式，通过射线追踪的方法对SFOC的最佳馈源位置和最佳馈源指向进行了优化设计。
