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: Monitoring and compensating for environmental and other conditions affecting antenna elements of an antenna is described. The conditions may affect radio frequency (RF) liquid crystal of the antenna elements. In one embodiment, the antenna comprises a physical antenna aperture having an array of surface scattering antenna elements that are controlled and operable together to form a beam for the frequency band for use in holographic beam steering and a compensation controller to perform compensation on the antenna elements based on monitored antenna conditions.

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 is disclosed herein for a direct drive mechanism for driving cells (e.g., liquid crystal (LC) cells, RF MEMS cells, etc.). In one embodiment, the antenna comprises an antenna element array having a plurality of antenna elements with each antenna element having one or more cells (e.g., liquid crystal (LC) cell, RF MEMS cell, etc.); drive circuitry coupled to cells in the antenna element array to provide a voltage to each of the cells; and memory to store a data value for each cell to determine whether the cell is on or off.
