摘要

在这种通信中，提出了一种具有两个半环形天线单元的纺织品多输入多输出(MIMO)天线。该天线覆盖6.95 ~ 16.46 GHz频谱，分数带宽为81.24%。它满足国际电联频段(7.25-7.75/7.9-8.4 GHz)全x频段(8-12 GHz)和ku频段下行-上行(11.7-12.2/14-14.5 GHz)应用频段。通过使用缺陷接地结构(DGS)，在工作频带内获得了非常高的端口隔离(> 15.5 dB)。该天线提供了极低的包络相关系数(ECC9.95 dB)。得到了不同输入激励相位角下的总主动反射系数(TARC)曲线。这也证实了天线具有很好的阻抗特性。所有这些以及稳定的辐射模式使天线成为理想应用频段中合适的MIMO进气道。

Textile Multiple Input Multiple Output Antenna for X-Band and Ku-Band Uplink-downlink Applications

In this communication, a textile multiple input multiple output (MIMO) antenna with two half ring shaped antenna elements is presented. The antenna covers the frequency spectra from 6.95 to 16.46 GHz with a fractional bandwidth of 81.24 %. It fulfills the ITU band (7.25-7.75/7.9-8.4 GHz) full X-band (8-12 GHz) and Ku-band downlink-uplink (11.7-12.2/14-14.5 GHz) application bands. Very high port isolation (> 15.5 dB) is obtained over the operating frequency band by using defected ground structure (DGS). The antenna provides very low envelope correlation co-efficient (ECC<0.09) and channel capacity loss (CCL<0.23 bits/s/Hz) whereas very high diversity gain (DG>9.95 dB) is obtained. Total active reflection coefficient (TARC) curve is found using different input excitation phase angles. This also confirms very good impedance behaviour of the antenna. All of these along with stable radiation patterns make the antenna a suitable MIMO aspirant in desired applications band.
