Wearable Ring Resonator Antenna [PDF]
physica status solidi (a), 2018 In this paper a metamaterial wearable antenna is proposed. The proposed design is based on a transmission line coupled to a pair of double ring resonators (DRRs) on an e‐textile substrate. The metallic antenna layer is fully embroidered providing both electromagnetic and mechanical good properties.
