The design of a printed monopole antenna on the system circuit board of the mobile phone for achieving GSM850/900/1800/1900/UMTS operation with a small area of 10 mm × 60 mm is presented. The antenna is easy to fabricate at low cost and mainly comprises a driven strip, a coupled strip, and a high‐pass matching network for providing two wide operating bands at about 900 and 1900 MHz to cover GSM850/900 and GSM1800/1900/UMTS operations, respectively. The wide lower band is controlled by the driven strip excited as a quarter‐wavelength mode, which is further tuned to become a dual‐resonance excitation by incorporating the high‐pass matching network for effective bandwidth enhancement. For the wide upper band, it is formed by a quarter‐wavelength mode excited at about 1800 MHz by the coupled strip and the higher‐order mode contributed by the driven strip. Furthermore, with the proposed antenna structure, the lower and upper bands can generally be tuned separately, which is an attractive feature and makes it easy to design for practical applications. © 2008 Wiley Periodicals, Inc.
