Abstract :
An omnidirectional antenna is presented. It is composed of dipole array. This antenna operates at 2.4 GHz for WLAN. As the radiation element, the dipole has a minimized height for reducing the size of antenna. Its size is 27mm high and 75mm length. Four dipoles that encircle a metal cylinder at the radial direction form an omnidirectional element. Along the axial direction there are three omnidirectional elements with the distance of 101mm. The gain of this antenna is 7.1 dBi at 2.4 GHz and the gain variation in azimuth plane less than 0.5dB.
