摘要： An antenna for ultra-wide band communication is disclosed. The antenna includes a substrate, a patch formed on one side of the substrate so as to be smaller than the substrate, and being excited when an electric current is supplied through a feeder line, so as so radiate energy, and a ground area formed by removing a portion of another side of the substrate so as to obtain a wide band characteristic.
