This paper presents the radiation characteristics of two planar microstrip arrays which are mechanically arranged so that they share one of their border. For both the planar arrays, the phase profile of array excitation has been chosen to get a focused radiated field at a point in the antenna near-field region. This structure is suggested to enhance the field strength and reduce the spot size, with respect to a single planar focused array. A numerical parametric study over some geometrical parameters is given, to show the focusing performance of the proposed configuration.

Abstract
This paper presents the radiation characteristics of two planar microstrip arrays which are mechanically arranged so that they share one of their border. For both the planar arrays, the phase profile of array excitation has been chosen to get a focused radiated field at a point in the antenna near-field region. This structure is suggested to enhance the field strength and reduce the spot size, with respect to a single planar focused array. A numerical parametric study over some geometrical parameters is given, to show the focusing performance of the proposed configuration.File in questo prodotto:
