【摘要】 本文提出了一种E波段端射型双极化磁电偶极子天线。通过介质切角及添加反射壁等方式分别完善了两种线极化天线的辐射特性,并共用金属壁集成双极化。此端射双极化天线的垂直极化工作频带60.8 GHz～96.7GHz (相对带宽45.6%)、水平极化工作频带65.0 GHz～78.6 GHz (相对带宽18.9%),由该单元组成的8元阵列在两个极化方向上的增益分别为15.1 dBi、13.3 dBi,且均可实现±30°波束扫描。更多还原

【Abstract】 An end-fire dual-polarized magnetoelectric dipole antenna for E-band is proposed in this paper.The radiation characteristics of two kinds of line polarization antennas are improved by dielectric substrate chamfer and adding reflective wall,and the dual polarization is realized by sharing metal wall integration.The vertical polarization band of dual-polarized antenna is 60.8 GHz～96.7 GHz(45.6% relative bandwidth) and the horizontal polarization band is 65.0 GHz～78.6 GHz(18.9% relative bandwidth),and the gain of the 8-element array composed of this unit is 15.1 dBi and 13.3 dBi in the two polarization directions,and both can achieve ±30° beam scan.更多还原
