Abstract: A method and apparatus for impedance matching for an antenna aperture are described. In one embodiment, the antenna comprises an antenna aperture having at least one array of antenna elements operable to radiate radio frequency (RF) energy and an integrated composite stack structure coupled to the antenna aperture. The integrated composite stack structure includes a wide angle impedance matching network to provide impedance matching between the antenna aperture and free space and also puts dipole loading on antenna elements.

Abstract: A unit cell can be used for a metasurface, metamaterial, or beamforming antenna. The unit cell includes a metal layer attached to a substrate. The metal layer defines an iris opening for the unit cell. One or more tunable capacitance devices are positioned within or across the iris opening. Each tunable capacitance device is to tune resonance frequency of the unit cell. Mass transfer technologies or self-assembly processes may be used to position the tunable capacitance devices.

Abstract: Methods and apparatuses are disclosed for a free space segment tester (FSST). In one example, an apparatus includes a frame, a first horn antenna, a second horn antenna, a controller, and an analyzer. The frame has a platform to support a thin film transistor (TFT) segment of a flat panel antenna. The first horn antenna transmits microwave energy to the TFT segment and receives reflected energy from the TFT segment. The second horn antenna receives microwave energy transmitted through the TFT segment. The controller is coupled to the TFT segment and provides at least one stimulus or condition to the TFT segment. The analyzer measures a characteristic of the TFT segment using the first horn antenna and the second horn antenna. Examples of a measured characteristic includes a measured microwave frequency response, transmission response, or reflection response for the TFT segment. In one example, the TFT segment is used for integration into a flat panel antenna if the measured characteristic of the TFT segment indicates the TFT segment is acceptable.
