Abstract

This paper presents a dual-band 2×2 MIMO antenna for WLAN applications. The design consists of four Planar Inverted-F Antennas with shorting pin. The 2×2 MIMO system has four ports and each antenna is a transceiver. The antennas are fed through a coaxial feed with an input impedance of 50 ohms. Decouplers are kept between the antennas to increase isolation and reduce mutual coupling. Each antenna can operate at 2.4 GHz and 7.54 GHz. At 2.4 GHz, the reflection coefficients S11, S22, S33, S44 are -13.0761 dB, -13.4858 dB, -12.9771 dB and -12.8324 dB respectively. At 7.54 GHz the reflection coefficients S11, S22, S33, S44 are -8.33 dB, -8.02 dB, -7.95 dB and -8.099 dB respectively. The isolation coefficients are S12, S21, S34 and S43. At 2.4 GHz, S12 and S21 are -16.65 dB, S34 and S43 are -17.02 dB. At 7.54 GHz, S12 and S21 are -34.51 dB, S34 and S43 are -35.53 dB. Also, by decreasing the width of the patch of PIFA, the resonant frequencies increase.

用于WLAN应用的双频MIMO天线

本文提出了一种用于WLAN应用的双频2×2 MIMO天线。该设计由四个带短引脚的平面倒f天线组成。2×2 MIMO系统有四个端口，每个天线是一个收发器。天线通过同轴馈电，输入阻抗为50欧姆。在天线之间保留去耦器以增加隔离并减少相互耦合。每个天线的工作频率分别为2.4 GHz和7.54 GHz。在2.4 GHz时，反射系数S11、S22、S33、S44分别为-13.0761 dB、-13.4858 dB、-12.9771 dB和-12.8324 dB。在7.54 GHz时，反射系数S11、S22、S33、S44分别为-8.33 dB、-8.02 dB、-7.95 dB和-8.099 dB。隔离系数分别为S12、S21、S34和S43。在2.4 GHz时，S12和S21为-16.65 dB, S34和S43为-17.02 dB。在7.54 GHz时，S12和S21为-34.51 dB, S34和S43为-35.53 dB。同时，通过减小PIFA贴片的宽度，谐振频率增加。
