改变微带天线基板形状实现圆极化

实现微带贴片天线圆极化的方法中,传统方法主要是设计适当的金属贴片形状和选择适当的馈电方式,而一种新思路即设计适当的介质基板形状,在某些使用环境中可以提供较大的方便。通过计算发现新思路有其可行性和工程价值,在某些方面有其独特的优势。

Circular Polarization Realization for Microstrip Patch Antenna by Changing Dielectric Shapes

Among the methods of circular polarization realization for microstrip patch antenna,the traditional methods are to select the proper shape of metal patch and the proper feeding style.A new method is to design the shape of the dielectric instead of the metal patch.Calculations and simulations show that this new method is feasible and convenient,and it has unique advantage in certain environments.
