摘要
基于传统交叉偶极子天线,设计了一款应用于全球定位系统 (GPS)的宽带圆极化天线。该天线用一个 50 .的同轴线给交叉偶极子馈电,通过一对四分之一空置印刷环使振子臂之间形成 90°相位差以产生圆极化辐射。为了拓展阻抗带宽和轴比 (AR)带宽,在耦合贴片上进行切角、开缝处理。Ansoft HFSS仿真结果显示,阻抗带宽 (|S11|<-10 dB)为 66.7%(1.141~2.283 GHz),3 dB轴比带宽为 33.3%(1.347~1.885 GHz)。在工作频段内最大圆极化增益为 8.2 dBi,圆极化特性良好,实现了带宽展宽的目的。
Abstract
Based on the traditional crossed dipole antenna, a wideband circular polarization antenna used in Global Positioning Systems(GPS) is designed. The crossed dipole is fed with a 50 . coaxial line. The crossed dipole can produce circularly polarized performance because of the orthogonal arms of dipoles with the phase difference of 90° due to a pair of vacant-quarter print rings. To achieve a broader impedance bandwidth and Axial Ratio(AR) bandwidth, the coupling patch is cut and slotted. Simulation results in Ansoft HFSS show that the antenna has an impedance bandwidth(|S11|<-10 dB) of 66.7% (1.141-2.283 GHz) and a 3 dB bandwidth of 33.3%(1.347-1.885 GHz). It has the maximum circular polarization gain of 8.2 dBi at the operating bandwidth. It has good circular polarization characteristics and the bandwidth can be expanded.
