摘要：
In this paper, a broadband circularly polarized (CP) antenna is designed on the basis of characteristic mode analysis (CMA). It is proposed that the broadband CP characteristics of the antenna are coupled by the coupling of a C-shaped monopole antenna operating at a higher frequency and a C-shaped slot antenna operating at a lower frequency. The final simulation results of the proposed antenna are as follows: the impedance bandwidth and the axial ratio (AR) bandwidth are 65`)/0(2.7GHz-5.24GHz) and 52.9%(3.2GHz-5.5GHz), respectively.
