A 5 GHz beam steering array for portable wireless MIMO application

A compressed footprint high gain beam steering parasitic antenna array is introduced for 5 GHz WLAN application in portable wireless devices. The collinear dipole array (consisting of a number of driven and parasitic dipoles) beam can be steered in 0, 60, and -60 degrees in the azimuth plane with the help RF switches. The peak gain of the array ranges from 11.7 to 12.2 dBi.
