Coplanar waveguide monopole antenna on artificial magnetic conductor for body-worn wireless communication systems

Abstract : We report in this paper the design and the realization of a monopole antenna directly placed over an artificial magnetic conductor (AMC) without the need of additional space between them. Simulation results and measurements are in good agreement and show that the antenna performances are as good as the best ones reported so far in literature while having a smaller volume. The antenna works at 1.916 GHz with a bandwidth of 8%. The adaptation of the antenna is-35 dB. Measurement of the antenna gain is 4.7 dBi with a front-to-back radiation ratio of 15.8 dB. Simulation results also show that the AMC isolates well the monopole from of the body: the localized SAR value calculated with 1 g of tissue is 0.34 W/kg with an injected power of 1W. The antenna with the AMC is well adapted for wearable applications.
