摘要：
A wideband circularly polarized (CP) printed antenna is proposed in this paper. This antenna is evolved from a bow-tie dipole antenna, which have wideband impendence bandwidth (IBW). It uses a configuration of rotational symmetry dipole structure to be radiators. This rotational symmetry structure makes the surface currents to produce a circular polarization wave. A 2x2 antenna array is also designed. The IBW of single and array antenna for S-11<-10dB is 140.6% (1.91-10.95GHz) and 140.6% (1.91-10.95GHz), respectively. The 3-dB axial ratio bandwidth (ARBW) of single and array antenna is 96.6% (3.70-10.62G11) and 96.6% (3.70-10.62G11), respectively.
