一种双模圆极化贴片天线设计

内容简介:为满足卫星导航系统的要求,采用单点馈电叠层贴片技术,设计了一种双频圆极化宽波束天线;采用隐式的时域有限差分方法,对天线进行全波仿真,分析了影响匹配性能的结构参数,并通过在贴片的一组对边上开矩形缝隙,微调天线谐振频率,同时实现了阻抗带宽和轴比带宽相吻合;总结出改善天线双频匹配特性的方法,解决了双频段同时达到最佳匹配的问题。

Abstract:To satisfy the satellite navigation system, a wide-beam antenna is designed with dual-frequency and circular polarization by using a single feeded two truncated patches. For these designing processes, an alternating- direction implicit finite-difference time-domain method has been used to simulate the antenna with full wave. The geomitrie parameters of the antenna is analyzed which effects the match properties. Two rectangular patches are slotted to tune the fequency, both impedance and axis-ratio bandwidth can be matched concurrence. Dualband matching performance has been realized at the same time. Three operational modes are studied, and methods improved the match properties of the dualband antenna have been concluded. The design parameters has been optimilized.
