Abstract
An electronically beam-steerable full-duplex phased array antenna is described. The phased array antenna includes an array of a plurality of radiating elements. The array includes at least one column having a plurality of radiating elements, and the array is configured to generate a radiation field. The phased array antenna includes a metasurface over the array of radiating elements. The metasurface introduces a phase shift to the radiation field of the array, to cause a beam of the phased array antenna to be angularly offset from the radiation field of the array.
Claims19
A beam-steerable phased array antenna comprising:
- an array of a plurality of radiating elements, the array including at least one column having a plurality of radiating elements, the array being configured to generate a radiation field;
- and
- a metasurface over the array of radiating elements, the metasurface introducing a phase shift to the radiation field of the array, to cause a beam of the phased array antenna to be angularly offset from the radiation field of the array.
A base station comprising:
- a phased array antenna for transmission and reception of wireless communications, the phased array antenna comprising:
- an array of a plurality of radiating elements, the array including at least one column having a plurality of radiating elements, the array being configured to generate a radiation field;
- and
- a metasurface over the array of radiating elements, the metasurface introducing a phase offset to the radiation field of the array, to cause a beam of the phased array antenna to be angularly offset from the radiation field of the array;
- a transmitter coupled to the phased array antenna for providing a transmit signal;
- and
- a receiver coupled to the phased array antenna for receiving a receive signal.
