The antenna is proposed to be the main piece of a necklace. It works for the 2.4 - 2.5 GHz industrial, scientific and medical (ISM) band. It also works for other bands such as 5.564 - 5.65 GHz, 6.79 - 6.973 GHz, 7.7614 - 7.883 GHz and 8.5 - 8.65 GHz with a small size of 40 × 50 mm2 and robust performance. The proposed design showed to have many appealing features such as small size, conformity and multi-band functionality and, thus, it could be a good candidate for IoT wearables.
Key words: Internet of things; Specific absorption rate; Spiral flower; Wearable antennas.
