Circularpolarization microstrip antenna has many excellent properties, which in wireless applications play an important role to play.
圆极化微带天线具有很多优良的特性，因而在无线应用中扮演着十分重要的角色。
2
Under certain axis ratio bandwidth, the circularpolarization axis ratio of the optimized cross dipole antenna can reach 1.
在一定轴比带宽条件下，优化后的十字振子天线正交方向上圆极化轴比可以达到1。
