Abstract : A wideband and radiation pattern recon-figurable vector antenna is proposed for dual-polarized and 3-D direction finding applications. Compared with the state of the art, this antenna achieves the accurate estimation of the direction of arrival of an incoming vertically-or horizontally-polarized electromagnetic field over a wider bandwidth (7:1). Measurement results are in good agreement with the simulated results obtained from full-wave electromagnetic simulations. Index Terms-wideband magnetic and electric dipoles, Vivaldi antennas, vector sensor, direction-of-arrival antenna, dual-polarized antenna, reconfigurable antenna.
Keywords : reconfigurable antenna. dual-polarized antenna direction-ofarrival antenna vector sensor Vivaldi antennas wideband magnetic and electric dipoles
