Abstract. Results of investigation
of super wideband multi-beam hybrid antenna on the base of Luneburg lens and a
clustered array are presented. Forming cluster elementary radiators are excited
by a multi-channel power divider. Applying approximate models the main
parameters of the antenna: gain, main beam beam-width, radiation pattern, level
of beam crossing are evaluated. Application of antenna Vivaldi array as a
clustered array is discussed.
Keywords: super wideband antenna, multi-beam
