A novel design of rectangular slot‐antenna with dual‐broadband operation for 2.4/5‐GHz wireless local area networks (WLANs) is proposed. With the use of two rectangular strips inset along the center line of the rectangular‐slot antenna, a new resonant mode close to the second operating mode of the regular rectangular slot antenna is excited to enhance the operating bandwidth of the higher band. And, the obtained impedance bandwidths for two operating bands can reach about 11% for the 2.4‐GHz band and 24.8% for the 5‐GHz band and cover the required bandwidths of IEEE 802.11b/g (2.4–2.484 GHz) and IEEE 802.11a (5.150–5.950 GHz). Details of the antenna design and the experimental results are presented and discussed. © 2005 Wiley Periodicals, Inc.
