Preliminary results on the performance of near field focused planar microstrip arrays working at 1.8 GHz have been shown, with reference to an 8 times 8 array with linear and circular polarization. Contour plots for the field at 1.5 m from the antenna aperture have been provided. Experimental results will be shown at the conference. To reduce cost production, future prototypes will be made of four...
In this paper, path loss measurements performed with low cost MicaZ modules used for on-body wireless sensor networks have been shown. By combining the experimental activities with simulation results based on simple canonical geometries, it has been possible to extract some simple path loss models. Time domain properties of the field attenuation are also under investigation. The path loss data will...
