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.

Abstract:

A communication system for point to multipoint communications by grouping client devices based on associated modes is provided. In one example implementation, point to multipoint communication improvements are achieved by grouping a plurality of client devices by their optimal modes for communication. For example, the communication system can determine, based on channel quality indicators (CQIs) that two client devices of a plurality of client devices are associated with an optimal first mode of a modal antenna. The system can group the two client devices into a first group, the first group associated with communication using the first mode of the modal antenna. The modal antenna can communicate with the first group using the first mode of a modal antenna during a single frame of communication.
