Abstract
Abstract:
The active impedances of the elements of planar finite phased arrays of dipoles are
investigated for excitations which produce either pencil beam or fan beam radiation
patterns with low side-lobe levels produced by tapered excitations. It is found that with
tapered excitations the elements impedances in the array change considerably with beam
scanning when compared with the case of uniform excitation.
