A novel dual‐broadband Y‐shaped monopole antenna with dual shorted I‐shaped strip‐sleeves for 2.4/5.2/5.8‐GHz wireless local area networks (WLANs) is proposed. Dual I‐shaped strip‐sleeves are introduced to be shorted with the ground plane to excite the upper resonant mode for operating at the 5.8‐GHz band. The obtained impedance bandwidths reach about 48.5% for the 2.4‐GHz band and 35.5% for the 5‐GHz band, which meet the required bandwidth specifications of IEEE 802.11a/b/g standards. The measured peak antenna gains for the operating frequencies across dual WLAN bands are measured to be 4.7 and 4.9 dBi, respectively, with gain variations within 0.5 dBi. © 2006 Wiley Periodicals, Inc.
