A wearable ultra-wideband monopole antenna with flexible artificial magnetic conductor

This paper introduces a thin film-based wearable ultra-wideband (UWB) antenna implemented over an artificial magnetic conductor (AMC) in order to reduce the effect of human body and improve gain and bandwidth characteristics. The proposed AMC is implemented using a low-cost and easily-fabricated polydimethylsiloxane (PDMS) as a flexible substrate to enhance radiation properties of the wearable antenna. The antenna used in this paper is based on a thin film of polyester and copper implemented in printed circuit board technology. The antenna and AMC are designed and simulated and the performance of the final design is verified in CST Microwave Studio.
