Abstract :
It is shown how the concept of phase mode excitation of circular antenna arrays may be extended to spherical arrays, and in particular that a spherical phase mode of the excitation function of a spherical array results in a far field radiation pattern with the same spherical phase mode form. A number of applications and issues concerned with the practical implementation are discussed.
