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.

Ultra-wide band antenna and plug-and-play device using the same

A broadband dipole antenna includes a dielectric substrate, a first radiating portion, a second radiating portion, a substantially U-shaped or V-shaped feed gap, and two feed points. The feed gap is located in-between the first radiating portion and the second radiating portion. The two feed points are located in the first radiating portion and the second radiating portion, respectively, and separated by the feed gap.

Broadband dipole antenna

A broadband antenna is capable of generating an upper resonant mode (at about 700 MHz) from a first radiating arm and a lower resonant mode (at about 500 MHz) from a second radiating arm. The first and second radiating arms are bent at least one time. An open end of the second radiating arm is extended toward an open end of the first radiating arm with a predefined distance there between. The predefined distance can be adjusted to improve the impedance matching of lower resonant mode, which can be further combined with the upper resonant mode to achieve a broad bandwidth covering the complete spectrum of digital TV channels (470-862 MHz).
