本文提出了一种适用于GPS的新型锥形四丝螺旋天线。该天线具有宽波束宽度和圆极化特性。数值模拟表明，俯仰角和辐射臂长度是影响这种天线波束宽度的主要因素。所设计的中心频率为1.5968 GHz的模型天线具有以下特点：1)约180度的3分贝波束宽度满足半球辐射要求；2)约0。3)1.5：1覆盖1.5859~1.6075 GHz下的驻波比。文中给出了天线的设计细节和仿真结果，并进行了讨论。
In this paper, a novel conical quadrifilar helical antenna for GPS application is presented. The antenna behaves wide beamwidth and circular polarization. Numerical simulations show that the pitch angle and the length of radiating arms are main factors which influence the beamwidth of this kind of antenna. The model antenna designed working at center frequency of 1. 5968GHz characterizes: 1) about 180 degrees of 3dB beamwidth which satisfies the requirement of the hemisphere radiation, 2) about 0. 35 GHz of 3dB axial ratio bandwidth, and 3) VSWR under 1. 5 : 1 covering 1. 5859~1. 6075 GHz. Details of the antenna design along with simulated results are presented and discussed.
