Abstract: The Internet of Things proposes the connectivity of domestic, medical and industrial devices through wireless solutions, and in various applications, such as wearable technology and flexible and resistant structures. Antennas are devices used at the edge of wireless telecommunications systems. In this work, a flexible wearable spiral printed circuit board antenna is developed, applied to the narrowband Internet of Things, operating in the 880 MHz band, and built in flexible dielectric, polyamide laminate. From the results it was observed that the spiral antenna obtained an omnidirectional radiation pattern, with a bandwidth of 10 MHz and a gain of 5.5 dBi.
