Dual-band LoRa Antenna: Design and Experiments

Abstract : In this study, a dual-band miniature antenna for LP-WAN covering 433MHz and 868MHZ bands is designed to fit into a 90*30mm terminal. Design methodology based on the use of two lumped components inserted in the radiating element is presented. The optimized antenna is fabricated and assembled with electronic components and battery. A measurement is performed to assess radiation performance in anechoid chamber. The terminal has a total efficiency of −6dB and −4.5dB at respectively 433MHz and 868MHz with a dipolar radiation pattern. The performance of the terminal is evaluated in a real environment and show similar performance at 433MHz and 868MHz.
