Printed and multiple antenna which is available to mobile handset is proposed and investigated in this paper. The proposed antenna is comprised of meandered transmission lines on the printed circuit board (PCB) substrate which is FR4(ε r=4.6). Especially, this antenna is based on composite right/left handed (CRLH) metamaterial transmission lines. In order to have a broad bandwidth, the antenna consists of two different unit cells. Through these two CRLH unit cell, this antenna can have a broad bandwidth which is from 1700 MHz to 2700 MHz (VSWR<3.0), and efficiencies of each frequency range are over 60%. Return loss, efficiency, radiation patterns, and current distributions are provided in this paper. Total PCB size is 40x80 mm2 with 1 mm thickness, and antenna space is 40x15 mm2. The proposed antenna covers a variety of commercial bands which are DCS, USPCS, WCDMA, Wibro, Bluetooth, and Wimax. Since this metamaterial antenna consists of transmission lines on PCB, proposed antenna is very useful to apply for the RF devices.
