摘要

The generation of focalized beams in the near-field (NF) with a circular antenna array are presented. The phase distribution for phase array launchers are first studied and explained. Gaussian excitation producing the same focalization effect in the NF are also discussed. Perfectly collimated beams in the NF and also generated with circular antenna arrays are discussed and theoretical examples are presented. Those collimated beams are Bessel ones of order 0 and higher.
