A Compact Quad-band Planar Antenna for LoRa IoT Applications

This work proposes a compact, Quad-band, high-efficiency Long Range (LoRa) planar antenna for IoT applications. LoRa is adopted in several settings: connected cities, smart irrigation, Mechanization, and the biosphere. These proficiencies create LoRa a good and economical option for wireless networking over far distances and in energy-efficient devices for IoT applications. The antenna has dimensions of 80mm X 50mm X 1.6mm. Mainly this antenna operates at four frequencies 0.9, 1.2, 1.8, and 4.9 GHz. The resonant frequency 0.9 GHz is applicable for LoRa Applications, and the remaining frequencies 1.2, 1.8, and 4.9 GHz are applicable for IoT applications.
