摘要

介绍了一种用于室内MIMO基站的正交双极化复合天线。该复合天线由垂直极化盘加载单极子和水平极化陷波阵列组成。所提出的天线不仅结构紧凑,外形低,而且磁盘加载单极子的阻抗带宽超过300 MHz,缺口阵列的阻抗带宽超过155 MHz。此外,该天线在水平面上具有全指向性,可满足室内顶棚基站的要求。

Bandwidth enhancement of a compact dual-polarized indoor base station antenna
An orthogonally dual-polarized composite antenna for indoor MIMO base station is introduced in this paper. The composite antenna consists of a vertically polarized disk loaded monopole and a horizontally polarized notch array. The proposed antenna has not only very compact structures and low profile, but also enhanced impedance bandwidths of over 300 MHz for the disk loaded monopole and 155 MHz for the notch array. Besides, the antenna has omni-directivity in horizontal plane to satisfy the requirement of indoor ceiling base station.
