Abstract
An antenna system is provided. The antenna system includes a modal antenna disposed on a circuit board. The modal antenna includes a driven element and a parasitic element. The modal antenna is operable in a plurality of different modes. Each of the plurality of modes has a distinct radiation pattern. The antenna system further includes a radio frequency amplifier circuit disposed on the circuit board. The radio frequency amplifier circuit is coupled between the drive element of the modal antenna and a transmission line.
