Abstract
The present invention relates to a bent folded dipole antenna for reducing a beam width difference, which can reduce a beam width difference, varying with a frequency band, and generate dual polarization through the use of an antenna structure having a bent folded dipole antenna unit, in which a plurality of bent folded dipole components is connected to each other as a single pattern, and a feeding unit for feeding a signal to the folded dipole antenna unit. Therefore, the present invention is advantageous in that it can reduce a beam width difference varying with a frequency band, simplify the structure of the antenna to reduce the cost thereof, and easily obtain dual polarization characteristics and wide band characteristics by combining a feeding unit for feeding a signal in a dual feeding manner with the bent folded dipole antenna unit implemented as a single pattern. In addition, the present invention is advantageous in that current flowing into the feed point of the feeding unit is induced only in folded dipole components without flowing into another feed point, thus realizing excellent isolation characteristics.
