A wideband circular polarization quasi magnetic-electric dipole antenna with single feed

摘要

A new broadband circularly polarized quasi magnetic-electric dipole antenna with single feed is proposed. The electric dipole is a pair of metal strip while the magnetic dipole is a pair of vertical shorted metal plate. The currents on the electric and magnetic dipoles exhibits an inherent phase difference of 90°, therefore the wideband circular polarization performance can be achieved. The simulation results show that -10dB reflection coefficient bandwidth is 35.9% (2.06-2.96GHz) and 3dB axial-ratio bandwidth is 44.3% (1.79-2.81 GHz).
