N2 - In this letter, a planar printed multiple-band antenna is proposed for mobile handset applications. The antenna consists of a driven monopole with multiple branches, and a parasitic ground strip with an open slot. By properly tuning the dimensions and positions of each part of the proposed antenna, octa-band operation is achieved with good radiation efficiency. For lower frequency, the LTE700, GSM850, and GSM900 bands are provided by the λ /4 modes of the driven monopole and the parasitic ground strip. For upper frequency, the DCS, PCS, UMTS, LTE2300 and LTE2500 bands are covered by the higher order modes of the driven monopole and the parasitic ground strip. The open slot and the shorter driven branch are utilized to widen the bandwidth in the upper frequency. All the mentioned operating bands are achieved in a small area of 15 × 602. The measured -6 -dB reflection coefficient bandwidth is 405 MHz (660∼ 1065MHz) in the lower band and ranges from 1665 MHz to more than 3000 MHz in the upper band.
