摘要:本文研究一款用于北斗卫星导航系统的小型化、双频段2×2天线阵列,工作于北斗系统的B3和B1频段,中心频点分别为1268.52MHz 和 1561.098MHz。为了实现圆极化,对阵列中的线极化的天线单元进行了连续旋转馈电。本文采用一体化设计方法可将天线阵列单元间间距降到任意小,实现阵列小型化。最终样品尺寸为120mm×120mm,性能满足设计要求。

Design of a Small Circularly Polarized Dual Band Antenna Array for Compass Satellite Navigation Applications
Abstract:A small circularly polarized dual band 2×2 antenna array for Compass satellite navigation applications is presented in this paper, which is operating at B3 and B1 Compass bands, respectively centered at 1268.52 and 1561.098MHz. And the circular polarization of the array is realized by a sequential rotation feeding scheme. In order to minimize the antenna array, an integrated design process is used, in which the separation between the antenna elements can be assumed to be arbitrarily small. The dimension of the small array is only 120mm×120mm and a good performance has been achieved.
Keywords: Small antenna array axial ratio bandwidth
