Combined Wide-Angle Scanning by a Two-Dimensional Dipole Array

Abstract

An analytical solution of an impedance synthesis problem for a two-dimensional dipole antenna array is obtained. The array consists of thin impedance electric dipoles whose centers are located at nodes of a planar rectangular grid with double periodicity. Radiation patterns of each dipole in the array does not differ from that of an isolated dipole. A new method for wide-angle scanning of the array radiation pattern, combining the simultaneous variation of phases of the excitation currents in the dipoles and of their surface impedances is proposed.
