A miniaturized Planar Inverted-F Antenna (PIFA) design tailored for wearable devices is presented in this work. The proposed antenna operates in the ISM band (from 2.4 to 2.5 GHz) used by common wireless communication standards. A felt textile substrate is used to allow easy integration into everyday clothing. A side-fed coaxial cable is also adopted to give a low profile. To assess human exposure, SAR analysis is conducted on the designed antenna and simulated results are presented. The SAR level of the antenna is successfully limited to comply with international guidelines, by introducing significant modifications on the antenna parameters.
