Abstract
A Ultra WideBand (UWB) substrate type dipole antenna is provided which has a stable radiation pattern. The UWB substrate type dipole antenna includes a dielectric substrate, a first radiator formed on a side of the dielectric substrate, a signal line transmitting an energy from a coaxial cable to the first radiator, and a plurality of second radiators formed at a predetermined distance from the first radiator and the signal line, and respectively having therein a plurality of slits of a predetermined configuration. Because there is no leakage of electric current to an outer part of an external conductor of the coaxial cable, even when the connection of the connector and the coaxial cable to the antenna, distortion of the radiation pattern of the antenna is prevented. As a result, the same radiation pattern and the direction of maximum radiation may be obtained before and after connection with the connector and the coaxial cable.
