BAN antenna design using ferrite polymer composite

Wearable antennas are an integral part of body area networks (BAN). Antenna design for BAN applications is a challenging task since the antennas have to be small, efficient and must not be affected by the wearer´s body. This makes isolation of antenna a matter of importance. Ferrites form an opaque media for microwave at the ISM frequencies and hence it could be used for the isolation of antenna from surroundings. Thin polymeric ferrite sheets are used to reduce body influence in BAN perspective.
