Abstract :
A method of designing a dual-frequency circularpolarization patch antenna array composed with four patch elements and a feeding network here. The design formulas are provided in detail. The antenna designed by the method is directly fed by a 50 Omega microstrip line feeder, and doesn´t need drilling in printed circuit board , thus it´s easy to fabricate and suitable for normal application. Then an example of patch antenna working at 1.9 GHz and 2.4 GHz in the manner of circular-polarization is given. The return loss, axial ratio and radiation pattern all meet the design requirements according to the simulation results given by ADS software.
