Abstract
An antenna structure for small wireless communication devices includes multiple antenna elements to achieve diversity and uniform hemispherical coverage gain. Individual patch antennas are located on separate surfaces of a polyhedron or hemispherical dome structure. The antenna structure is well-suited for operation at high frequencies, including the 5 to 6 GHz band. The antenna elements and RF circuitry can be combined in a small integrated enclosure, and the structure is suited for use in a base station of a WLAN.
