A printed dipole antenna showing high gain (about 6.8 dBi) radiation in the azimuthal plane is presented. The dipole antenna has a narrow width of 10 mm and a total length of about 202 mm (with 1.64 wavelengths of the frequency at 2442 MHz, the center frequency of the 2.4‐GHz WLAN band). In each one of the two radiating arms of the dipole antenna, a meandered line is inserted as a phase‐reversal device. With this arrangement, the proposed dipole antenna performs as a collinear array antenna with three in‐phase half‐wavelength radiating elements, leading to constructive radiation in the azimuthal plane and small side lobes in the elevation plane. © 2005 Wiley Periodicals, Inc.
