ABSTRACT:
An antenna is provided having a relatively wide bandwidth of operation. The antenna may be a printed circuit board dipole antenna having a ladder balun feed network coupled to a ground plane and dipole radiating elements located about one-quarter wavelength from an edge of the ground plane. The ground plane acts as a reflector to increase antenna gain. A plurality of the antennas may be provided in an array configuration with antennas being located in relatively close proximity and being isolated from other antennas in the array. An array of antennas may be used to provide a wireless link in a wireless network utilizing a IEEE 802.1X frequency band.
