Triple-Band Antenna for IoT and 5G Applications using Metasurfaces and Polygon Slot

A compact triple-band antenna is designed for internet of things (IoT) applications including Bluetooth, Zigbee, Wi-Fi, WiMAX, WLAN, industrial IoT (IIoT), Medical Body-Area Networks (MBAN), and Wireless Body Area Network (WBAN) which are operating from 2 GHz to 5 GHz. The proposed antenna having tri-band response resonating at 2.44 GHz, 3.20 GHz and 5.05 GHz, while considering return loss S

< -10 dB and 3-dB bandwidths of 60MHz, 200 MHz and 270 MHz respectively at resonant frequencies. Moreover, the proposed antenna is presenting improved efficiency and gain according to the recent requirements of wireless networks. This antenna has reduced dimensions, ideal to be integrated in most of IoT devices. In addition, the parameters of an antenna such as ground plane, polygon slot and material structures are optimized for better performance.
