Zusammenfassung:	A wideband and reconfigurable radiation pattern vector antenna is proposed for dual-polarized and three-dimensional 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.
