INTERNAL ANTENNA WITH WIDEBAND CHARACTERISTIC

摘要

Disclosed is an internal antenna having wideband characteristic. According to the present invention, the internal antenna having wideband characteristic which includes a printed circuit board, a first antenna unit fed with electricity from a feeding unit of the printed circuit board, and a second antenna unit spaced apart from the first antenna unit by a predetermined distance and indirectly fed with electricity by means of coupling to the first antenna unit, wherein the second antenna unit is indirectly fed with electricity with a phase difference from the first antenna unit due to an electric distance from a feeding point of the first antenna unit.
