A multiple input, multiple output (“MIMO”) antenna system is provided for operation on a radio frequency (“RF”) module that may be used in a wireless access device. The MIMO antenna system includes a plurality of multi-band antenna elements connected to a radio in a MIMO configuration. The multi-band antenna elements and the radio are configured to operate on an RF module. A reflector is formed on the RF module to contain the plurality of multi-band antenna elements and a common director is positioned in front of the multi-band antenna elements to concentrate signal communication in a sector. The plurality of multi-band antenna elements are oriented to provide a sector coverage pattern formed by beam patterns generated by each of the multi-band antenna elements.
