ABSTRACT:
An ultra-wide band (UWB) antenna and a plug-and-play (PnP) device using the same are provided. A dielectric substrate of the PnP device has a ground plane. The UWB antenna includes a radiating metal plate and a feeding portion. The radiating metal plate is in a non-ground region of the dielectric substrate and has at least a slit cut. An opening of the slit cut is at the edge of the radiating metal plate facing the ground plane. The feeding portion is also at the edge of the radiating metal plate facing the ground plate for feeding a signal to the antenna.
