摘要

无线通信通常用于计算机外设、移动设备、家用电器等设备上发送或交换信息。每个设备都嵌入无线模块，产生电磁，因此产生干扰的可能性很大。控制干扰的方法之一是控制信号的发射和功率，因此本研究设计了可重构MIMO天线来控制天线的辐射方向图，以减少无线通信中的干扰问题。该天线设计在2.4 GHz频段，因为大多数和常用的设备外设使用未经许可的频段以及无线保真(Wi-Fi)。设计的天线为4×4 MIMO，工作频率为2.4 GHz和2.6 GHz，适用于无线局域网(WLAN)和长期演进(LTE)。系统辐射方向图使用Arduino微控制器来驱动PIN二极管切换光束。仿真和测量结果与单天线和2×2和4×4 MIMO的配置一致。该天线工作在2.387 ~ 2.628 GHz之间，而模拟和测量的反射系数至少为- 24.3 dB。MIMO天线设计用于改善数据通信，特别是在移动通信系统中。

Reconfigurable MIMO Antenna for Wireless Communication Based on Arduino Microcontroller

Wireless communication is common use on devices to send or exchange information such computer peripheral, mobile device, home appliances, etc. Every device embedded with wireless module and contribute electromagnetic, thus high possibility of occurring interference. One of method how to control interference is by controlling signal to transmit as well as power, thus in this research designed reconfigurable MIMO antenna to control antenna radiation pattern to reduce interference issue in wireless communication. The antenna designed in 2.4 GHz band because most and common use of devices peripheral using unlicensed band as well as for Wireless Fidelity (Wi-Fi). The designed antenna is 4×4 MIMO which operate at 2.4 and 2.6 GHz for Wireless Local Area Network (WLAN) and Long Term Evolution (LTE). The system radiation pattern is configured using an Arduino Microcontroller to driven PIN diode to switch he beam. Simulations and measurements are in good agreement with the configuration of the single antenna and 2×2 and 4×4 MIMO. The antenna is operational between 2.387 and 2.628 GHz, whereas the simulated and measured reflection coefficients are obtaining at least −24.3 dB. The MIMO antenna designed to improve data communication, especially in mobile communication systems.
