SMALL ULTRA WIDEBAND ANTENNA HAVING UNIDIRECTIONAL RADIATION PATTERN

摘要

PROBLEM TO BE SOLVED: To disclose an ultra wideband (UWB) antenna designed to have a unidirectional radiation pattern.;SOLUTION: The UWB antenna includes a substrate; a power feeding part, provided on an upper surface of the substrate, for receiving a power supply of an external electromagnetic energy; a dipole radiator excited by the electromagnetic energy fed through the power feeding part and radiating electromagnetic waves; and a loop radiator respectively enhancing and canceling the electromagnetic waves radiated by the dipole radiator so as to have a unidirectional radiation pattern.;COPYRIGHT: (C)2006,JPO&NCIPI
