A wideband internal antenna that is composed of a coupled feeding part and four branch lines is presented.The proposed antenna can operate within two wide bands of 0.64–0.99 GHz and 1.65–2.85 GHz which cover 11 service bands including LTE 700/2300/2500, AMPS800, GSM900, DCS1800, PCS, UMTS, WiBro2350, ISM/Bluetooth, and WLAN for the 4G mobile phone. The antenna could be available not only for future 4G service but also for current 2G/3G services. This internal antenna is fabricated within the limits of a 65 × 11 × 7 mm 3 volume and suitable for smart phones or personal digital assistant (PDA) applications. The measured results are in agreement with the simulation. © 2012 Wiley Periodicals, Inc. Microwave Opt Technol Lett 54:513–516, 2013; View this article online at wileyonlinelibrary.com.
