ABSTRACT:
A UWB antenna has an upper dielectric, a lower dielectric, and a conductive pattern sandwiched therebetween. The conductive pattern has a vertex apart from a feeding point with a predetermined gap. The conductive pattern has a reversed triangular portion having a right-hand taper part and a left-side taper part which widen from the feeding point at a predetermined angle toward a right-hand side surface and a left-hand side surface, respectively, and a semicircular portion having a base side being in contact with an upper side of the reversed triangular portion. The UWB antenna further has a feeding pattern connected to the feeding point, whereby carrying out feed from the feeding pattern to the conductive pattern by electromagnetic coupling.
