摘要
提出了一种具有双圆极化特性的宽带磁电偶极子。该天线由四个水平辐射片、四对垂直辐射片、一个接平面、一对宽带馈电网络以及作为宽带三级阻抗匹配过渡的新型交叉馈电结构组成。将包含威尔金森功率分压器和耦合线移相器的馈电网络印在接平面底部，可以提供稳定的双向正交相位宽带信号输出。该天线作为ME偶极子工作，在1.71GHz至2.95GHz的右圆极化(RHCP)和1.7GHz至3.25GHz的左圆极化(LHCP)范围内分别具有53.2% (S11 <−10 dB, AR < 3 dB)和62%的宽工作带宽。
DUAL CIRCULARLY POLARIZED WIDEBAND MAGNETO-ELECTRIC DIPOLE ANTENNA FOR WIRELESS APPLICATIONS
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.
