Abstract
A wideband magneto-electric (ME) dipole with characteristics of dual-circular polarization is presented in this paper. The proposed antenna is composed of four horizontal radiation patches, four pairs of vertical radiation patches, a ground plane, a pair of wideband feeding networks, and novel crossed feeding structures which work as wideband 3-stage impedance matching transitions. The feeding networks which contain a Wilkinson power divider and a coupled-line phase shifter are printed on the bottom of the ground plane, and they can provide stable two-way output wideband signals with quadrature-phase. The proposed antenna works as a ME dipole with a wide operation bandwidth of 53.2% (S11 < −10 dB, and Axial Ratio (AR) < 3 dB) from 1.71GHz to 2.95GHz for right-hand circular polarization (RHCP) and 62% from 1.7GHz to 3.25GHz for left-hand circular polarization (LHCP), respectively.
