An Integrated Frequency Tunable MIMO Antenna for IOT Applications

Abstract

This paper presents a dual-polarized reconfigurable MIMO antenna for IoT applications using pin diodes. The proposed antenna covers a wideband from 3.3 GHz to 6 GHz (5G band) and also switches between two resonating frequencies 2.4 GHz - Zigbee and 5.8 GHz - WLAN. However, the developed antenna achieves the gain and efficiency of about 4 dBi and 80 % respectively. The designed antenna also achieves ECC less than 0.08 and a diversity gain of around 9 dB. The antenna is modeled in Computer Simulation Tool (CST).
