双馈点圆极化贴片天线的设计与仿真

Design and Simulation of Circulary Polarized Patch Antennas with Dual Feedings

文中介绍了圆极化天线的特点和分类。圆极化天线对于提高通信系统的抗多径能力具有明显的效果。文中采用了双馈点、相位相差90°的方法来实现圆极化,此方法设计相对简单。最后通过HFSS有限元仿真软件,对天线进行分析调试和仿真,给出了仿真结果及详细的理论推导过程和相关特性曲线。

This paper introduces the characteristic and classification of circulary polarized patch antennas, which are effective in enhancing the ability of communicating systems to avoid multiple routes. Two feedings whose phase differs by 90° are used to achieve circulary polarization, which is easy to design. HFSS is used to modulate and simulate the antenna with the simulation result, theoretical derivation and related characteristic curves given.
