Abstract

A compact multiband antenna using a composite right/left‐handed transmission line (CRLH‐TL) zeroth‐order resonator (ZOR) for global system for mobile communications (GSM900/1800/1900, 880‐960/1710‐1880/1850‐1990 MHz), wideband code division multiple access (WCDMA, 1920–2170 MHz), and wireless broadband (WiBro, 2.3–2.4 GHz) operations is presented. The proposed antenna having a total volume of 35 mm × 5 mm × 3 mm comprises a lower band ZOR antenna part and an upper band ZOR antenna part. The zeroth‐order resonant properties are described and analyzed using dispersion diagrams based on the CRLH‐TL ZOR theory and the full‐wave simulation. The radiation patterns are the same as the omnidirectional characteristics and the maximum gains are 1.64, 2.47, and 3.32 dBi at 0.92, 1.88, and 2.2 GHz, respectively. © 2009 Wiley Periodicals, Inc.
