Abstract

A 2x1 compact UWB-MIMO antenna with two -10 dB impedance bandwidths of 2.6 GHz and 8.85 GHz is presented. The MIMO antenna dimension is 5.3 cm ´ 3.8 cm and is composed by two symmetrical rectangular patches, each one with a resonance frequency at 4 GHz. An EBG structure is introduced between the elements to increase de isolation and improve the MIMO antenna performance. The transmission coefficient of the MIMO antenna with EBG structure reaches a minimum of -28.9 dB at 8.18 GHz, and its maximum is -16.1 dB at 9.9 GHz. The impedance bandwidth is 5.9 GHz, and the maximum gain of the proposed antenna is 6 dBi.

用于超宽带应用的紧凑型MIMO天线

提出了一种2x1紧凑型UWB-MIMO天线，具有2.6 GHz和8.85 GHz两个-10 dB阻抗带宽。MIMO天线尺寸为5.3 cm × 3.8 cm，由两个对称的矩形贴片组成，每个贴片的谐振频率为4ghz。在元件之间引入了EBG结构，以增加隔离性，提高MIMO天线的性能。采用EBG结构的MIMO天线在8.18 GHz时传输系数最小为-28.9 dB，在9.9 GHz时传输系数最大为-16.1 dB。阻抗带宽为5.9 GHz，最大增益为6dbi。
