摘要

本文提出了一种紧凑的双极化多输入多输出(MIMO)天线，用于超宽带应用。该天线由两个准自互补(QSC)辐射元件组成，使得天线无需额外的去耦结构即可获得高隔离度。元件以微带线馈电并垂直放置以获得极化分集。在WiMAX系统中，可以通过在每个辐射元件中刻蚀1 / 4波长的弯曲槽来实现切陷带。采用半波长槽埋入地面，四分之一波长槽埋入辐射单元，可获得WTAN系统的缺口带。结果表明，10dB回波损耗的阻抗带宽范围为2.3 ~ 12 GHz，抑制频带分别为3.3 ~ 4 GHz和5.1 ~ 6 GHz。

Compact dual-polarized UWB-MIMO antenna with two band-notched function

This paper presents a compact Dual-polarized multiple-input-multiple-output (MIMO) antenna with two band-rejection for UWB applications. The antenna consists of two quasi-self-complementary (QSC) radiating elements, which make the antenna obtain high isolation without an additional decoupling structure. The elements are fed with microstrip lines and placed perpendicularly to obtain polarization diversity. Notched band at WiMAX system can be realized by etching a quarter-wavelength bent slot in each of the radiating elements. Notched band at WTAN system can be obtained by using a half-wavelength slot embedding in the ground and a quarter-wavelength slot embedding in the radiating element The proposed antenna with a total size of 35 × 35mm2 has been fabricated and measured. The results show the impedance bandwidth with 10dB return loss ranging from 2.3 to 12 GHz, and two rejected bands which cover 3.3 to 4 GHz and 5.1 to 6 GHz.
