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.
Claims18
An antenna system comprising:
- a modal antenna operable in a plurality of modes, each of the plurality of modes having a distinct radiation pattern;
- an amplifier;
- a first switching device configured to selectively couple the modal antenna to a transmission line via a first path that includes the amplifier;
- a second switching device configured to selectively couple the modal antenna to the transmission line via a second path that bypasses the amplifier;
- and
- one or more processors configured to transmit a control signal to the first switching device via the transmission line.
An antenna system comprising:
- a modal antenna operable in a plurality of modes, each of the plurality of modes having a distinct radiation pattern;
- an amplifier;
- a first switching device configured to selectively couple the modal antenna to the amplifier;
- a second switching device configured to selectively couple the amplifier to a transmission line;
- and
- one or more processors configured to transmit a control signal to at least one of the first switching device or the second switching device via the transmission line.
A method for controlling operation of an antenna system comprising a modal antenna configurable in a plurality of modes, each of the modes having a different radiation pattern, the method comprising:
- communicating a control signal over a transmission line to a radiofrequency circuit of the antenna system;
- controlling operation of one or more switching devices of the radiofrequency circuit based, at least in part, on the control signal to couple the modal antenna of the antenna system to the transmission line via a first path that includes an amplifier of the radiofrequency circuit;
- obtaining, via the modal antenna, a radiofrequency signal;
- and
- providing the radiofrequency signal to the transmission line via the first path that includes the amplifier of the radiofrequency circuit.
