Abstract :
A design of a broadband circularly-polarized (CP) slot antenna is proposed in this paper. The CP radiation of the slot antenna is excited by the proximity coupling of a microstrip line. To obtain a broad CP bandwidth, three CP modes contained in the CP band are excited. The results show that the proposed antenna can provide a CP operating bandwidth of 56% (3.17 GHz-5.65 GHz) within an impedance bandwidth of 64% (2.96 GHz-5.75 GHz).
