提出了一种简单而新颖的设计方法，用于设计一种双频工作的螺旋折叠印刷四线螺旋天线（S-FPQHA）。传统PQHA的轴向长度通过曲折和将螺旋臂变成方形螺旋的形式而被小型化约43%。进行参数研究，以探讨性能的改善。在此基础上实现了一种工作在L1/L5 GPS应用中的双频天线，具有良好的增益和圆极化特性。实测结果验证了这一概念。
A simple and innovative method for designing a spiral folded printed quadrifilar helix antenna (S-FPQHA) for dual-band operations is presented. The axial length of a conventional PQHA is miniaturized of about 43% by meandering and turning the helix arms into the form of square spirals. Parametric studies are performed to explore the performance improvements. Based on the studies a dual band antenna working in L1/L5 GPS application is realized with a good gain and a good circular polarization. Measured results are presented to validate the concept.
