PHASED ARRAY ANTENNA ABSORBER AND ASSOCIATED METHODS

摘要

A phased array antenna (100) includes a substrate (104), and an array of dipole antenna elements (40) on the substrate (104). Each dipole antenna element (40) includes a medial feed portion (42), and a pair of legs (44) extending outwardly therefrom. Each dipole antenna element (40) further includes a passive load (304), and a switch (302) connected thereto for selectively coupling the passive load (304) to the medial feed portion (42) so that the dipole antenna element (40) selectively functions as an absorber fo r absorbing received signals while the passive load (304) dissipates energy associated therewith.
