A novel dual-band antenna made of a narrow, rectangular, flat metal plate for wireless local area network (WLAN) operation in the 2.4- and 5.2-GHz bands is presented. The antenna comprises a larger radiating arm, a smaller radiating arm, and a shorting portion. The larger and smaller radiating arms control a lower resonant mode at about 2.4 GHz and an upper resonant mode at about 5.2 GHz, respectively, and are connected to each other through the shorting portion. The antenna is easily excited by using a 50Omega mini coaxial line and shows good antenna performance. The proposed antenna design is described and experimentally studied.
