A low‐cost, one‐piece, flat‐plate dipole antenna for dual WLAN band operation is presented. The dipole antenna is rectangular in shape with the dimensions 10 mm × 37 mm and fed by 50‐Ω mini‐coaxial cable. By cutting two L‐shaped slits in each radiating arm, two dipole arms are obtained, which form a larger dipole and a smaller dipole antennas for the 2.4‐ and 5‐GHz band operation, respectively. The dipole arms are further short‐circuited, making it possible for the antenna to be fabricated by stamping a single, flat metal plate only. The impedance bandwidth for 2.4/5‐GHz WLAN operation is with VSWR below 1.5 and good omnidirectional radiation patterns are also observed. © 2008 Wiley Periodicals, Inc.
