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 40 times 40 cm<sup>2</sup> identical printed panels, connected by a suitable coaxial-cable feeding network. Finally, work is in progress to extend the research activity to systems operating at 2.4 GHz and down to 900 MHz.

Abstract
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 40 times 40 cm2 identical printed panels, connected by a suitable coaxial-cable feeding network. Finally, work is in progress to extend the research activity to systems operating at 2.4 GHz and down to 900 MHz.File in questo prodotto:
