Abstract
A system may include a radio frequency chain configured to process a signal. The system may further include a reconfigurable antenna including multiple antenna feeds, each of the antenna feeds associated with a beam direction. The system may also include a beam selection network configured to couple the radio frequency chain to a first antenna feed of the multiple antenna feeds to generate a first beam in a first direction, and simultaneously couple the radio frequency chain to a second antenna feed of the multiple antenna feeds to generate a second beam in a second direction.

A system comprising:
- a radio frequency chain configured to process a signal;
- a reconfigurable antenna including multiple antenna feeds, each of the antenna feeds associated with a beam direction;
- and
- a beam selection network configured to couple the radio frequency chain to a first antenna feed of the multiple antenna feeds to generate a first beam in a first direction, and simultaneously couple the radio frequency chain to a second antenna feed of the multiple antenna feeds to generate a second beam in a second direction.
A method comprising:
- processing a signal at a first radio frequency chain;
- and
- routing a first signal component between the first radio frequency chain and a first antenna feed of a first reconfigurable antenna to generate a first beam in a first direction, and simultaneously routing the first signal component between the first radio frequency chain and a second antenna feed of the first reconfigurable antenna to generate a second beam in a second direction.
A method comprising:
- processing a first signal at a radio frequency chain to generate a first modulated signal;
- routing the first modulated signal from the radio frequency chain to a first antenna feed of a reconfigurable antenna to generate a first beam in a first direction, while simultaneously routing the first modulated signal from the radio frequency chain to a second antenna feed of the reconfigurable antenna to generate a second beam in a second direction;
- determining a phase difference between the first signal and a second signal;
- and
- shifting a phase of the first modulated signal at the second antenna feed to generate a second modulate signal corresponding to the second signal, wherein the first modulated signal is transmitted via the first beam and the second modulated signal is transmitted via the second beam.
