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 disposed on a circuit board, the modal antenna comprising a driven element and a parasitic element, the modal antenna operable in a plurality of modes, each of the plurality of modes having a distinct radiation pattern;
- a radio frequency (RF) amplifier circuit disposed on the circuit board, the RF amplifier circuit coupled between a transmission line and the driven element of the modal antenna;
- and
- one or more control devices configured to transmit one or more control signals to the RF amplifier circuit via the transmission line.
An antenna system, comprising:
- a modal antenna disposed on a first circuit board, the modal antenna comprising a driven element and a parasitic element, the modal antenna operable in a plurality of modes, each of the plurality of modes having a distinct radiation pattern;
- a radio frequency (RF) amplifier circuit disposed on the first circuit board, the RF amplifier circuit coupled between the driven element of the modal antenna and a transmission line coupling the first circuit board to a second circuit board;
- and
- one or more control devices disposed on the second circuit board, the one or more control devices configured to transmit one or more control signals to the RF amplifier circuit via the transmission line.
A method for controlling operation of an antenna system comprising a modal antenna and a RF amplifier circuit, the modal antenna and the RF amplifier circuit each disposed on a circuit board, the method comprising:
- obtaining, via a driven element of the modal antenna disposed on the circuit board, a RF signal;
- amplifying, via the RF amplifier circuit disposed on the circuit board and coupled between the driven element and a single coaxial transmission line, the RF signal to generate an amplified RF signal;
- providing, via the single coaxial transmission line, the amplified RF signal to RF circuitry of the antenna system;
- and
- providing, via the single coaxial transmission line, one or more control signals to the RF amplifier circuit.
