Abstract

A simple method for designing a quad antenna element Ultra Wideband (UWB) Multiple Input Multiple Output (MIMO) antenna is presented in this work .The presented quadelement UWBMIMO antenna is printed on substrate FR4having the dimension of 110×119×1.5 mm3.The four elements of antenna are orthogonally positioned with each other for improving isolation. For achieving further isolation between elements of antenna, a metallic parasitic strip having plus shape is printed in ground. The proposed antenna design has obtainedS11<-11.4 dB at all four ports, insertion loss<-20.5 dB and additionally, attained almost omnidirectional pattern of radiation across the whole impedance bandwidth (2.43to 18.3 dB).Also, high diversity performance is obtained by proposed antenna design based on Envelope Correlation Coefficient (ECC<0.0003), Total Active Reflection Coefficient (TARC<-8.68 dB), Diversity Gain (DB ≈10) throughout the bandwidth, Multiplexing Efficiency(-0.15 to-1.3 dB), Mean Effective Gain Ratio (0.97 to -0.97dB ) and Channel Capacity Loss(<0.1 bits/sec/Hz).

四元超宽频MIMO天线阵列

本文提出了一种设计四元超宽带(UWB)多输入多输出(MIMO)天线的简单方法。所设计的四元超宽带(UWB)多输入多输出(MIMO)天线打印在尺寸为110×119×1.5 mm3的基板fr4上。天线的四个元件相互正交放置，以提高隔离度。为了实现天线各元件之间的进一步隔离，在地面上印制了具有加号形状的金属寄生条。所提出的天线设计在所有四个端口获得了s11 <-11.4 dB，插入损耗<-20.5 dB，此外，在整个阻抗带宽(2.43至18.3 dB)上获得了几乎全向的辐射方向图。此外，基于包络相关系数(ECC<0.0003)、总主动反射系数(TARC<-8.68 dB)、整个带宽的分集增益(dB≈10)、复用效率(-0.15 ~ 1.3 dB)、平均有效增益比(0.97 ~ -0.97dB)和信道容量损耗(<0.1 bits/sec/Hz)的天线设计获得了较高的分集性能。
