ABSTRACT:
An electrically small, dual polarized, hemispherical coverage, multi-element adaptive array antenna exhibiting low VSWR and operational over an octave of bandwidth is flush-mounted with the airframe structure of high performance aircraft. The antenna is configured as a cavity type structure in the shape of a regular polygon and has a plurality of radiation elements mounted on an insulative support board, each of the elements being is connected to a respective output port for use in a multi-channel adaptive array system. The array provides broadband capability of nulling interfering sources having arbitrary polarization and spatial direction.
