摘要： A MMIC amplifier is directly connected to the balanced feed points at the aperture of an antenna to eliminate the distance between electronics coupled to the antenna and the antenna itself, such that interfaces, components and connection lines which introduce losses and parasitic effects that degrade system performance are eliminated due the direct connection. Expanding the aperture of the antenna to accommodate the direct connection of a MMIC amplifier to balanced feed points of an antenna has been found to have no deleterious effects on antenna performance. Moreover, when coupling the MMIC amplifier to an unbalanced coaxial line, any associated ripple is minimized due to the direct connection.

摘要： A photonically controlled antenna array is made of a plurality of stacked light waveguides made of a material such as silicon whereon each of which one or more photonically controlled antenna elements are mounted. Light is injected into ones of the light waveguides and reflects therein until it is absorbed by the antenna elements mounted thereon due to the higher refractive index of silicon. When the photonically controlled antenna elements are illuminated they are switched to a conductive state and can transmit and receive electromagnetic signals. When no light is injected into the light waveguide the photonically controlled antenna elements are not illuminated and are in a non-conductive state wherein they cannot receive or transmit electromagnetic signals. One edge of each of the light waveguides is adjacent to a ground plane, and the antenna elements on each light waveguide are spaced from said ground plane a distance equal to a quarter wavelength at the frequency at which each of said photonically controlled antenna elements is designed to operate. The antenna elements radiate and receive signals in a direction parallel to said waveguides that is opposite to said ground plane.

摘要： A method and apparatus is provided for avoiding pattern blockage due to scatter from an object in which an artificial surface directs the energy from the antenna prior to arriving at a blocking structure such that either the wave fronts of the energy are linear when they arrive at the blocking structure or the phase of the energy incident on the object is adjusted such that the energy reflected from the object is in phase with energy directly from the antenna radiating elsewhere in the far field pattern, or both.
