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.
