Abstract
In this study, a simple structure designed antenna for 2G and 3G mobile communication applied to notebook computer (NB) is proposed and analyzed by finite difference time domain (FDTD). The proposed antenna has great characteristics of simple structure, easy production, low cost, good impedance matching, and wideband frequency. The antenna main structure is printed on 0.8 mm with permittivity 4.4 FR4 single‐sided PCB, which is bonded to metal bracket. This proposed antenna covers GSM 850/900/1800/1900 and WCDMA multibands and satisfies NB wireless wide area network system. Both FDTD simulation and measurement show that the antenna gain is 2.2 dB for 800 MHz band and 4.6 dB for 1800 MHz band. The 3‐dB passbands are about 136 (824–960 MHz) and 460 MHz (1710–2170 MHz), respectively. The bandwidth of each passband is matched with the desirable values for the NB multiband requirement. © 2009 Wiley Periodicals, Inc.
