    Abstract: A method and apparatus for RF ripple correction in an antenna aperture are described. In one embodiment, the antenna comprises: an array of antenna elements having liquid crystal (LC); drive circuitry coupled to the array and having a plurality of drivers, each driver of the plurality of drivers coupled to an antenna element of the array and operable to apply a drive voltage to the antenna element; and radio-frequency (RF) ripple correction logic coupled to the drive circuitry to adjust drive voltages to compensate for ripple.

    Abstract: A method and apparatus for testing radio-frequency antenna elements are disclosed. In one embodiment, the apparatus comprises: a frame having a platform to support an array of radio-frequency (RF) antenna elements of a flat panel antenna having antenna elements; a first antenna to transmit microwave energy to subsets of RF antenna elements of the segment and to receive reflected microwave energy from the subsets of RF antenna elements; a filter between the segment and the first antenna, the filter comprising an opening positioned over each of the subsets of RF antenna elements at different times to expose said each of the subsets of RF antenna elements to microwave energy transmitted by the first antenna; a second antenna to receive microwave energy transmitted though the subsets of RF antenna elements at the different times; a controller coupled to the subsets of RF antenna elements and to provide at least one stimulus or condition to the subsets of RF antenna elements; and an analyzer to provide stimulus to the subsets of RF antenna elements and to measure a characteristic of the array using one or both of the first antenna and second antenna.

    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.
