A novel, compact, coaxial‐line‐fed mobile‐unit antenna for wireless wide area network operation in the GSM850/900/1800/1900/UMTS bands is presented.The antenna consists mainly of one slit‐embedded ground plane and two radiating strips, all printed in a coplanar configuration on a small FR4 substrate with the overall dimensions 35 mm × 45 mm, which corresponds to 0.10λ × 0.13λ with respect to free‐space wavelength λ at the central frequency, 859 MHz, of the GSM850 band. In addition to compactness, the antenna is easily fed by minicoaxial cable, which allows it to be flexibly deployed inside wireless communications devices as an internal antenna. Experimental prototypes of the design are constructed, tested, and studied in detail in this article. © 2010 Wiley Periodicals, Inc.
