A new structure of an NFC loop antenna for mobile handset applications is proposed. The proposed antenna consists of conventional loop elements and a parasitic loop embedded capacitor to enhance its performance. Although the sintered ferrite sheets with higher relative permeability(μr≈200)have been used to reduce the performance deterioration due to the eddy current on the battery pack of a mobile handset, their costs are high, and they are considerably breakable. In this paper, with the proposed structure, we effectively enhance the performance of an NFC loop antenna by employing the ferrite-polymer composite with lower relative permeability(μr≈55).

Ethylene Propylene Diene Terpolymer

A series of organic- inorganic polymer composites were synthesized by incorporating Barium hexa ferrite (BHF) at different wt % in the Ethylene-propylene-diene terpolymer (EPDM) polymer matrix by adopting solution casting method. The synthesized EPDM/BHF polymer composite were characterized through different techniques i.e.; X-ray diffraction study, SEM(scanning electron microscope), dielectrical and electrical behavior in the frequency range 1 kHz to 1 MHz. A detailed study of the dielectric behavior i.e.; ε’ (dielectric permittivity), tan δ (dielectric loss), M’and M’’ (dielectric modulus) and σac (electrical conductivity) were reported in this communication. The XRD of the composites showed the uniform distribution of the filler particles in the polymer matrix. The SEM micrograph confirms the homogeneous dispersion and distribution of BHF particles in the EPDM polymer matrix. These polymer composite show a promising dielectric behavior which is different from its constituent components.
