Abstract
An antenna and electronic equipment having the same are disclosed. The antenna comprises: a radiator electrically connected to a feeder, and radiating an electric wave; and one or more reinforcing circuits disposed in the radiator so as to uniformly distribute a current on at least one part of the radiator. The antenna can have a length much shortened than a wavelength of an operation frequency with maintaining the same efficiency, thereby being able to be mounted even in electronic equipment such as a terrestrial DMB terminal operated at a low frequency bandwidth,
