This paper describes the design of a miniaturized multiband Inverted-F Antenna (IFA) suitable for integration in compact Internet-of-things (IoT) terminals. The antenna efficiently operates over the LoRa (915 MHz) and GPS L1 (1.57 GHz) and L2 (1.23 GHz) bands. Its dimensions are 13×25×1 mm3 (0.04×0.08×0.003 compared to the lower operating frequency) for a total device size of 40×25×10 mm3. Measurements of the antenna when integrated into an IoT position tracking device as well as of the whole terminal in a real application scenario are reported.

Abstract
This paper describes the design of a miniaturized multiband Inverted-F Antenna (IFA) suitable for integration in compact Internet-of-things (IoT) terminals. The antenna efficiently operates over the LoRa (915 MHz) and GPS L1 (1.57 GHz) and L2 (1.23 GHz) bands. Its dimensions are 13×25×1 mm3 (0.04×0.08×0.003 compared to the lower operating frequency) for a total device size of 40×25×10 mm3. Measurements of the antenna when integrated into an IoT position tracking device as well as of the whole terminal in a real application scenario are reported.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione
