Abstract

This paper presents a Bluetooth antenna for a smart jewellery with metallic covers on both sides. The antenna design is based on a non-resonant coupling element antenna. The designed antenna is capable of operating both in free space and near a human body, e.g. in the user's hand. The measured prototype achieves over 55 % total efficiency in the free space and over 35 % total efficiency when measured with a hand phantom in the 2.4-2.48 GHz frequency range.
