Abstract: A wireless industrial process filed device includes a process interface element configured to interface with a process fluid and control or sense a process variable of the process fluid. A controller is configured to control operation of the process interface element. An RF circuit board includes a plurality of RF transceivers carried on the RF circuit board, each configured to send and/or receive an RF signal which carries information related to the process variable. A plurality of antennas are carried on the RF circuit board and form an antenna array. Each of the plurality of antennas is coupled to at least one of the plurality of RF transceivers. Each of the plurality of antennas having a different antenna pattern. The controller controls operation of the plurality of RF transceivers to communicate with a remote device through an antenna array patterned formed by transmission of RF signals through the plurality of antenna patterns of the plurality of antennas.
