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 for absorbing received signals while the passive load (304) dissipates energy associated therewith.
