摘要

提出了一种表面开槽并增加辐射边框的新型贴片天线. 采用HFSS软件仿真的结果显示

它的阻抗带宽和轴比带宽相比普通单贴片天线增大很多

而且具有良好的增益和双频带特性

其双频带可以覆盖GPS/GLONASS/GALILEO/北斗四大卫星系统的L1和L2频段. 因此

非常适合用于手持式精确导航终端

以取代两片结构的双频贴片天线.与其他双频圆极化贴片天线相比

此新型贴片天线具有频带宽、尺寸小且剖面低等突出优点

具有良好的应用前景.

Abstract

A novel patch antenna with a slotted surface and a radiation frame is presented. HFSS software simulation results show that both the impedance bandwidth and the axial ratio bandwidth are significantly increased compared with the normal sole patch antenna

and higher gain together with better dual-band characteristics can be obtained as well. Its dual bandwidth is able to cover frequency band L1 and L2 of four satellite systems including GPS/GLONASS/GALILEO/Compass. Therefore

in place of the dual patch antenna

it is particularly suitable for the use of handheld high precision navigation terminals. Furthermore

this novel patch antenna has the advantages of wider bandwidth

smaller size and lower cross-section over other dual-band circularly polarized patch antennas

which leads to a promising prospect.
