Reduction of Mutual Coupling for Wearable Antennas

摘要

A novel metamaterial-inspired isolator which combines defected ground structures (DGS) and modified split ring resonators (SRR) is proposed. No vertical conducting parts are present, which have a risk of being broken due to user movements. It is also wideband and does not affect the compactness of the antenna array. Its most important characteristic is that it has a stable isolating performance under complex bending conditions. A prototype was fabricated and measured.
