An antenna system for a wireless digital device is provided. The antenna system includes an array of N antennas (N: integer) housed within a wireless digital device, each of the n antennas covering an angular sector in space approximately equal to 2*.pi./N radians in azimuth. The antenna system includes a mounting structure for arranging the antennas in a wireless digital device to provide a pseudo-omnidirectional electromagnetic spatial coverage such that the total azimuthal coverage toward the exterior of the wireless digital device is substantially spherical except for the direction of a user using the wireless digital device, and the combined antenna radiation patterns exhibit a strong null in the direction of the user.
