UWB ANTENNA HAVING FREQUENCY NOTCH BY PARASITIC STRIP

摘要

A UWB(Ultra-Wide Band) antenna having a frequency notch by a parasitic element is provided to freely adjust a frequency notch band even in completing the antenna. A UWB antenna includes a substrate, a radiating unit(30), a feeding unit(20), a grounding unit(50), and a parasitic element(40). The radiating unit is formed on a top surface of the substrate to radiate electric waves. The feeding unit is connected to the radiating unit on the top surface of the substrate to supply electric signals. The grounding unit is formed on a bottom surface of the substrate. The parasitic element is formed on the bottom surface of the substrate to face the radiating unit.
