Abstract A GSM/DCS/PCS internal antenna suitable to be embedded at the widened end portion of a promising USB dongle for wireless network access in a laptop computer is presented. The proposed internal antenna uses two separate resonant strips folded into a compact structure to generate two wide operating bands at about 900 and 1800 MHz to cover the GSM and DCS/PCS operations. In addition, although in a compact structure, the antenna's two resonant strips are designed to be less coupled, thus allowing the antenna's lower and upper bands to be adjusted separately, without affecting each other. Details of the USB dongle embedded with the proposed internal antenna are described, and experimental results are presented and discussed. © 2006 Wiley Periodicals, Inc.
