摘要
为了增大无线通信的信道容量,提高通信质量,利用差分进化算法和矩量法对天线的S 11和S 12进行联合优化,得到了一款小型多输入多输出(MIMO)超宽带天线,天线具有良好的隔离度。该方法相较于利用仿真软件优化,大大减小了工作量,提高了效率。仿真和实测的对比结果表明,所设计的天线性能优良,能够广泛地应用在短距离便携式无线通信系统中,有效提高了信道容量;此外,仿真和实测结果的吻合验证了本方法的正确性和有效性。
In order to enlarge the channel capacity and improve quality of wireless communication systems,a multiple input multiple output ultra-wideband(MIMO UWB)antenna with high isolation was designed by jointly optimizing S 11 and S 12 with differential evolution algorithm(DEA)and method of moments(MOM).Compared with the simulation software method,this method can greatly reduce the amount of work and improve efficiency.According to the comparison of the measured results and the simulated results,the proposed compact antenna can be widely applied in short distance wireless communication systems with good performance,and it can effectively improve the the channel capacity.Additionally,the measured results are consistent with the simulated results,demon-strating correctness and effectiveness of the method.
