具有稳定相位中心的双频段宽波束天线

The Dual-band Wide-beam antennas with fixed phase center

天线相位中心是影响系统性能的重要因素之一。对于双频段工作且需要宽波束覆盖的天线,实现稳定的相位中心,是一项难度较大的工作。该文设计了一种双频段交叉振子结构的天线,每个频段在上半空间范围内都具有稳定的相位中心。对该天线进行了电气性能仿真并测试,验证了这种天线具有稳定的相位中心。最后指出这种天线可用于导航定位等系统中,具有重要的工程应用价值。

The phase certer is an important factor which affects the performance of the system.It is difficult for an antenna to work with dual-band and wide-beam,and fixed phase certer.The paper gives an antenna with the corssed dipole structure,which has the fixed phase certer in the scope of the upper half space in every band.The antenna is emulated and measured,and the results can validate that the antennas can fulfil the demands.Finally,the paper points that the antenna can be used in navigation system,orientation system and so on,and has important application value in engineer.
