A novel dual‐band printed G‐shaped monopole antenna is proposed. The antenna provides two resonant paths of different lengths (forming into a G‐shaped profile) in order to achieve 2.4‐ and 5.2‐GHz dual‐band operation for WLAN applications. Reasonably large impedance‐matching bandwidth and good radiation patterns have been observed. The measured impedance bandwidth for 10‐dB return loss in the 2.4‐ and 5.2‐GHz bands reaches 0.37 GHz (2.25–2.62 GHz) and 1.06 GHz (4.94–6 GHz), respectively. In addition, the proposed antenna has a small size of 13.6 × 9.3 mm 2 . © 2005 Wiley Periodicals, Inc.
