A small‐size wideband internal mobile phone antenna formed by a planar strip monopole with a chip‐capacitor‐loaded loop radiating feed for achieving eight‐band long term evolution/wireless wide area network operation in the 698–960 and 1710–2690 MHz bands is presented. The antenna is suitable to be disposed on a small no‐ground board space (15 × 45 mm 2 ) of the system circuit board and enclosed by an L‐shaped system ground plane of the mobile phone. On the protruded ground of the L‐shaped system ground plane, a universal series bus connector for the data port of the mobile phone can be accommodated without affecting the antenna performances. The antenna also shows a low profile of 3 mm above the circuit board, which makes it very promising for slim mobile phone applications. The proposed antenna was fabricated and tested. Measured and simulated results are presented. The specific absorption rate results of the antenna are also analyzed. © 2011 Wiley Periodicals, Inc.
