    Abstract: A multibeam antenna and method of using the same are described. In one embodiment, the antenna comprises an aperture having a plurality of radio-frequency (RF) radiating antenna elements. The RF radiating antenna elements generate a plurality of beams simultaneously in different directions in response to a first modulation pattern for holographic beamforming applied to the plurality of RF radiating antenna elements to establish all beams of the plurality of beams such that antenna elements of the plurality of RF radiating antenna elements contribute to all beams in the plurality of beams concurrently. The antenna also includes a controller coupled to the aperture to generate the first modulation pattern.

    Abstract: An antenna apparatus having a peripheral radio-frequency (RF) choke with directional heat transfer is described. In some embodiments, an antenna apparatus comprises: an upper enclosure portion; a lower enclosure portion coupled to the upper enclosure portion to form an inner area; an antenna aperture having a plurality of antenna elements, the plurality of antenna elements to radiate radio-frequency (RF) energy and the antenna aperture to generate heat when in operation; and an RF choke gasket between, and forming a thermal communication, with the upper and lower enclosures to operate as an RF absorber to absorb RF energy and to directionally transfer the heat toward the upper enclosure.

    Abstract: Antennas with tunable elements and methods for using the same are disclosed. In some embodiments, an antenna comprises: a plurality of radio-frequency (RF) radiating antenna elements, wherein each antenna element of the plurality of RF radiating antenna elements comprises a tunable element, circuitry connected to the tuning element to set a voltage on the tunable element. In some embodiments, the circuitry comprises a voltage storage structure, a first transistor having a first gate connected to the voltage storage structure, a first source connected to the tunable element, and a first drain for coupling to a constant voltage source, and a data voltage input terminal operable to apply a voltage to the voltage storage structure and to the first gate to determine current through the first transistor.
