This article first antenna, microstrip theory, the circular polarization technology, the theoretical discussion, in this based on the microstrip antenna of circular polarization method - corner square microstrip antenna, and has done a design simulation , and then do the design and further research to improve and eventually get a resonant frequency (S11 reflection coefficient corresponding to the minimum frequency) for the 1.5GHz and 1.43GHz, the frequency of circular polarization for the 1.46GHz, S11 is less than -10dB relative bandwidth, the VSWR is less than 2 is about 8.8% relative bandwidth, axial ratio less than 3dB relative bandwidth of about 2.2% of the right circular polarization microstrip antenna design case, which proved very good the circular polarization microstrip antenna theory, also fully confirmed by a square corner design is a practical program, and select the appropriate regulation of sticks is indeed able to improve the performance of the antenna.

本文先对天线、微带理论、圆极化技术等进行了理论论述，在此基础上，提出圆极化微带天线的实现方法——切角方形微带天线，并对此做了设计仿真，后又对这一设计方案做了改进及进一步研究，最终得到一个谐振频率（反射系数S11 的最小值所对应的频率）为1.5GHz和1.43GHz，圆极化频率为1.46GHz，S11 小于-10dB 的相对带宽、驻波比小于2 的相对带宽约为8.8%，轴比小于3dB 的相对带宽约为2.2%的右旋圆极化微带天线的设计案例，从而很好的印证了圆极化微带天线理论，也充分证实了切角方形是一种切实可行的设计方案，而选取合适的调节枝则确能提高天线的性能。

All these many properties exist in a simple Here, where they interpenetrate each other. None of these has a different Here from the others; each is everywhere in the same Here where the others are. And at the same time, without being divided by different Heres, they do not affect each other in their interpenetration; its being white does not affect or alter the cubical shape it has, and neither affects its tart taste, and so on: on the contrary, since each is simple relation to self, it leaves the others alone and is related to these merely by being also along with them, a relation of mere indifference.

所有这些众多的特质都存在于这一个简单的这里，它们并且在这里互相贯穿起来；没有一种特质具有异于另一种特质的另一个这里，而每一种特质随便在何处都同别的特质一样存在于同一这里之中；并且同时它们并没有由于不同的这里把它们分离开，在这种贯穿在一起的情况下，它们又彼此互不相影响；盐的白色不影响或改变盐的方形，盐的白色和立方形两者又不影响或改变盐的咸味，既然由于每一特质本身都是简单的自我关联，它们互不干扰对方，它们彼此间只是通过那漫无差别的又联系起来。
