提出了一种用于多频段GPS接收机的圆极化天线的设计方法。该设计采用多层贴片的概念，通过一个单一的同轴探头。三个贴片通过狭缝和对称I形槽堆叠在一起，用于实现GPS的三个工作频带，包括L1（1.575 GHz）、L2（1.227 GHz）和L5（1.176 GHz）。所提出的天线已经实现了2.0%，1.5%和1.7%的带宽，在GPS L1，L2和L5波段，分别。它具有0.51 dB的最小轴比，在上半球具有GPS应用所需的宽波束宽度。所提出的天线的设计在实验中得到了验证。此外，进行了详细的分析，研究了不同的几何参数对天线性能的影响。
A novel design of a circular polarized antenna for multiband GPS receivers is presented. The design employs the concept of multistacked patches fed through a single coaxial probe. Three patches being stacked together with a slit and symmetry I-slot are used to achieve triple operating frequency bands for GPS including L1 (1.575 GHz), L2 (1.227 GHz) and L5 (1.176 GHz). The proposed antenna has achieved a bandwidth of 2.0%, 1.5%, and 1.7% at GPS L1, L2, and L5 bands, respectively. It exhibits a minimum axial ratio of 0.51 dB with broad beamwidth in the upper hemisphere required for the GPS applications. The design of the proposed antenna is verified in the experiment. In addition, a detailed analysis has been carried out to study the effects of different geometrical parameters on the performance of the antenna.
