Abstract

|A quad-element recon(cid:12)gurable radiation pattern Multiple Input Multiple Output (MIMO) antenna is designed for WLAN and 5G applications suitable for indoor wireless communications. It consists of four radiating elements that operate over triband frequencies 2.4, 3.5, and 5.5 GHz. Moreover, the pattern diversity is obtained by introducing two diagonally crossed slots in the radiator to steer the main beams of the antenna in 8 diﬀerent angular directions using eight PIN diodes. The overall physical dimension of the proposed antenna is about 0 : 55 (cid:2) 0 : 55 (cid:21) 0 . In addition, an Acrylonitrile Butadiene Styrene (ABS) enclosure is designed, and the performance of the proposed antenna is evaluated. The measurement results show that the proposed antenna has an impedance bandwidth of 4.18%, 14.13%, and 28.5% at the said frequencies, respectively.

用于室内无线通信的四元可重构辐射方向图MIMO天线

|四元侦察(cid:12)可靠辐射方向图多输入多输出(MIMO)天线专为适用于室内无线通信的WLAN和5G应用而设计。它由四个辐射元件组成，在三频带频率2.4、3.5和5.5 GHz上工作。此外，通过在散热器中引入两个对角线交叉的槽，使用8个PIN二极管将天线的主波束引导到8个不同的角度方向，从而获得方向分集。该天线的整体物理尺寸约为0:55 (cid:2) 0: 55 (cid:21) 0。此外，设计了ABS(丙烯腈-丁二烯-苯乙烯)外壳，并对该天线的性能进行了评估。测量结果表明，该天线在上述频率下的阻抗带宽分别为4.18%、14.13%和28.5%。
