This paper presents a multi-facet design of an array antenna for near-field focused applications. The cylindrical arrangement of a set of antenna panels (namely, focused linear arrays) will radiate fields focused at the center of the circle formed by the panels. Such an array configuration exhibits superior performance with respect to the conventional planar arrangement, if a symmetric focus region is demanded. Numerical simulations have been performed for arrays thought for RFID (Radio Frequency Identification System) reader antennas at 2.4GHz, as a function of the number of array panels and the focus distance from the antenna surface.

Abstract

This paper presents a multi-facet design of an array antenna for near-field focused applications. The cylindrical arrangement of a set of antenna panels (namely, focused linear arrays) will radiate fields focused at the center of the circle formed by the panels. Such an array configuration exhibits superior performance with respect to the conventional planar arrangement, if a symmetric focus region is demanded. Numerical simulations have been performed for arrays thought for RFID (Radio Frequency Identification System) reader antennas at 2.4GHz, as a function of the number of array panels and the focus distance from the antenna surface.
