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: A beam splitting hand off systems architecture and method for using the same are disclosed. In one embodiment, the method comprises: generating a first beam with a single electronically steered flat-panel antenna to track a first satellite; generating a second beam with the single electronically steered flat-panel antenna to track a second satellite simultaneously while generating the first beam to track the first satellite; and handing off traffic from the first satellite to the second satellite.

Abstract: A non-circular center-fed antenna and method for using the same are disclosed. In one embodiment, the antenna comprises: a non-circular antenna aperture with radio-frequency (RF) radiating antenna elements; and a non-radially symmetric directional coupler to supply a RF feed wave to the aperture at a central location within the antenna aperture to enable the feed wave to propagate outward from the central location to an edge of the aperture.

Abstract: Dual resonator for flat panel antennas is disclosed. In one example, an antenna comprises a single physical antenna aperture having at least two spatially interleaved antenna sub-arrays of antenna elements operable as two resonator sets with a frequency offset with respect to each other. The antenna sub-arrays are operated together to form a beam in the desired frequency band. Each sub-array has a modulation pattern calculated based on holographic beam steering algorithms. The frequency offset between the sub-arrays can be achieved, e.g., by geometrical differences of the radiative antenna elements or differences in electromagnetic loading of the radiative antenna elements. By using two or dual resonator sets with frequency offset, significant improvement to dynamic bandwidth can be achieved in contrast to a single resonator antenna by expanding the dynamic bandwidth range with dual resonators.

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.
