A new broadband circularly polarised printed antenna is proposed. 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 polarisation wave. The simulation and measurement results are very consistent. The results show good performance of IBW is ∼140.6% (1.91–10.95 GHz) for S 11 <−10 dB, 3 dB axial‐ratio bandwidth is ∼96.6% (3.70–10.62 GHz).
