Abstract
Antennas and methods for using the same are disclosed. In some embodiments, an antenna includes a metasurface having radiating antenna elements and amplifiers configured to amplify signals for the radiating antenna elements, wherein, for each of the radiating antenna elements, the metasurface includes one or both of: a receive path having a low noise amplifier (LNA) configured to amplify a first set of received signals, at least one radiating antenna element configured to receive the first set of received signals, and a transmit path having a power amplifier (PA) configured to amplify a second set of transmit signals, the second set of transmit signals to be transmitted from the one radiating antenna element.
Claims22
An antenna comprising:
- a metasurface having radiating antenna elements and amplifiers configured to amplify signals for the radiating antenna elements, wherein, for each of the radiating antenna elements, the metasurface includes one or both of:
- a receive path having a low noise amplifier (LNA) between a first coupling element and said each radiating antenna element, the LNA configured to amplify a first set of received signals, said each radiating antenna element configured to receive the first set of received signals, and
- a transmit path having a power amplifier (PA) between a second coupling element and said each radiating antenna element, the PA configured to amplify a second set of transmit signals, the second set of transmit signals to be transmitted from said each radiating antenna element;
- and
- a waveguide coupled to the metasurface.
