主　　题：Air dielectric Circular polarization Dual-feed Microstrip antenna 

摘      要：This paper describes a novel dual-feed circularly polarized antenna,and the dual feeding mode is realized by grooving on the antenna *** antenna utilizes air dielectric material to meet the requirements of low weight and *** results demonstrate that the antenna exhibits capacitive loading between the metal antenna patch and the ground floor,allowing for adjustment of the working frequency of the dual-feed circularly polarized microstrip ***,the original center frequency of 2.264 GHz was reduced to 1.582 GHz,facilitating antenna miniaturization and broad *** a return loss(S11)below-10 dB,a bandwidth of 72 MHz(1.552-1.624 GHz)was ***,the dual-feed microstrip antenna incorporates a 90°bridge,resulting in circular polarization gains of 2.26 dBi at 1.561 GHz and 2.45 dBi at 1.575 ***,the antenna design offers a large working bandwidth and excellent circular polarization characteristics,making it suitable for a wide range of applications in satellite navigation and positioning terminals.
