Abstract

A novel coplanar waveguide (CPW)-fed printed monopole antenna with an n-shaped slot for dual-band operations is proposed. By etching an n-shaped slot on the radiating element, two tunable operating bands can be obtained. The measured results indicate that the impedance bandwidths of the proposed antenna, defined by 10-dB return loss, are 13.6% (1.85–2.12 GHz) and 5.7% (2.39–2.53 GHz), covering the required bandwidths for PCS (1850.5–1989.5 MHz), CDMA2000 (1850–1990 MHz), TD-SCDMA (1880–2025 MHz), and 2.4 GHz WLAN (2400–2484 MHz). In addition, good omnidirectional radiation characteristics have been obtained over the entire frequency range of interest. © 2011 Wiley Periodicals, Inc.
