Abstract
In this paper, we proposed vertically structured radiator for increasing bandwidth and gain of mobile phone internal antenna. The proposed antenna has vertically structured radiator instead of planar structured radiator to improve the antenna characteristics for GSM850/900 and DCS1800/PCS1900 bands. The antenna improve bandwidth of low band with 28 % than planar structured radiator. and also, improve bandwidth of high band with 14 %, efficiency 31.80~86.36 %, average gain -4.956~-0.617 dBi on the GSM850/900 and DCS1800/PCS1900 bands. These results are good performance among the small antenna with vertically structured radiator for increasing bandwidth and gain.
