A Convenient Method to Design Dual-Frequency Circular-Polarization Patch Antenna

摘要：

In this paper,we propose a method to design a kind of dual-frequency circular-polarization patch antenna composed with two patch antenna elements and feeding network and provide detailed design formulas. It is convenient and rapid to obtain the antennas geometric parameters on the premise of providing enough precision. The antenna designed with this method is directly fed by microwave transmission line,and needs no drillingInprinted circuit board ,so its easy to make and suitable for normal application. ThenWe show an example-an antenna working at 1.9GHz and 2.4GHz in the manner of circular-polarization. According to the simulation results obtained by Agilent ADS software,the return loss,axial ratio and radiation pattern all meet the design requirements.
