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.
Claims28
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) 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.
A method for transmitting and receiving signals with an antenna having a waveguide and a metasurface coupled to the waveguide and having amplifiers to amplify signals being received by radiating antenna elements and signals to be transmitted by radiating antenna elements, the method comprising:
- receiving, by one radiating antenna element, a first set of received signals;
- amplifying, using a receive path having a low noise amplifier (LNA), the first set of received signals prior to being coupled to the waveguide;
- and
- coupling, via a coupling slot, the amplified received signals to the waveguide.
