A dual-band printed dipole slot antenna for wireless local area network operation has been designed. The proposed antenna is obtained by folded dual dipole slots operated at the half-wavelength mode. The antenna has a compact substrate size of 40 mm by 15 mm only. The antenna uses a T-shape microstrip fed line which can excite the dual slots to cover the operating bands 2.45 GHz (2.4 GHz - 2.484 GHz) and 5.25 GHz (5.15 - 5.35 GHz) WLAN band. The antenna has good radiation characteristics and good impedance bandwidth.
