摘要： A radio frequency antenna uses an array of spherical lens and mechanically movable radio frequency (RF) elements along the surface of the spherical lens to provide cellular coverage for a narrow geographical area. The antenna includes at least two spherical lens, where each spherical lens has an associated element assembly. Each element assembly has a track that curves along the contour of the exterior surface of the spherical lens and along which a radio frequency (RF) element can move. The antenna also includes a phase shifter configured to adjust a phase of the signals produced by the RF elements. The antenna includes a control mechanism configured to enable a user to move the RF elements along their respective tracks, and automatically configure the phase shifter to modify a phase of the output signals from the elements based on the relative positions between the RF elements.

摘要： Electromagnetic (EM) feeds can illuminate a standard primary reflective antenna with a plurality of feed beams each having a different orbital angular momentum (OAM) or polarization. The reflective antenna, which can be a non-OAM antenna, can reflect the feed beams and thereby produce a composite OAM transmission comprising each of the feed beams. A non-OAM primary antenna can thus transmit a plurality of OAM feed beams as a composite OAM transmission.

摘要： System for positioning a reflector includes a base (112), yoke (104) and a reflector in the form of a lens mirror assembly (10). A motor (120) is mounted and remains substantially stationary with respect to rotation about a first axis while the yoke rotates about the first axis. A connecting rod (152) actuated for movement by the motor is mechanically coupled to the reflector so that movement of the connecting rod in relation to the yoke imparts rotation to the reflector about the second axis when the reflector is supported by the yoke. A mechanical drive system couples an output shaft of the motor to the connecting rod. The mechanical drive system is arranged so that it varies an angular position of the reflector at a rate which is linearly related to the rotation of the output shaft.

Some of the multiple mini-hub terminals, and some of the multiple remote terminals are capable of wireless communication respectively with each other through satellite communication means. A co-located terminal is hard wire connected with at least some of the mini-hub terminals. At least some of the terminals includes a flat antenna comprising a ground plane and a substrate forming at least one in flat array antenna mounted relative to the ground plane. The flat array antenna has multiple spaced dipoles formed on the substrate to constitute the array, and a transmission line formed on the substrate connecting the spaced dipoles. The transmission line is for connection with a link to a terminal with which communication is to be affected by signals through the antenna. A mobile antenna has beam steering lenses for forcing the signal. Also provided are sensors located on power transmission lines, the sensor being capable of measuring travelling waves on the lines, and communicating via an array antennal through a satellite at KU, KA-band or L-band frequencies, characteristics of the travelling wave thereby to facilitate fault location on the transmission lines.

摘要： An antenna, particularly adapted to produce a scanning beam usable for radar and communication applications, includes a frame. Attached to the frame is a reciprocating device that is operatively connected to a reflecting conductor. Spaced by a uniform gap from the conductor is an elongated dielectric waveguide carried on a conductive layer of a laminate supported by the frame on an input side of the antenna. The waveguide covers a set of spaced apart apertures in the laminate conductive layer. Joined to the laminate conductive layer on an opposite output side of the antenna is a dielectric layer. On an outer surface of the laminate dielectric layer is a set of spaced apart conductive patches that align with the laminate conductive layer apertures. During operation of the antennas an electromagnetic wave is transmitted through the waveguide to pass through the laminate apertures and energizes the patches. At the same time, the reflecting conductor moves back and forth toward the waveguide to vary the uniform gap to induce a phase shift in the electromagnetic wave passing therethrough. Electromagnetic energy from the energized patches combines in phase to form an outward projecting beam of radiated energy that scans from side-to-side.

摘要： A mobile tracking antenna for microwave signals from a satellite or distant transmitter includes a micro- electromechanical system produced by semiconductor processing. Specifically several micro faceted reflector segments have their facets selectively controlled by a feedback control system and reflects the signal onto a four sector horn which then by error signals actuates electrostatic positioning means on the micro facets to center the signal on the optimum receiving portion of the horn. Each segment covers a portion of the 360.degree. receiving spectrum. The particular segment is selected by a maximum signal being received.

摘要： A compact scanned antenna which includes a radiator, a rotatable tube and a line source. The radiator is formed by plating a shaped dielectric core. It generates an antenna beam at an output aperture in response to a microwave signal at an input port. The line source generates a radiation sheet which is directed across a signal plane to the input pot. The tube has a cylindrical wall which is positioned across the signal plane. As the tube rotates, refractive or diffractive transmission structures pass through the signal plane. The refractive structures include linear segments which refract the wavefront of the radiation sheet. Because the wavefront slope at the radiator's aperture is a function of the wavefront slope at its input port, the antenna beam is scanned. The linear contour segments have the same inclination but are not colinear. This arrangement reduces the thickness of the tube wall. Phase coherence is achieved by an appropriate radial spacing of adjacent ends of contour segments. The diffractive structures are arranged to vary the spacing of diffraction rings as they pass through the signal plane. This produces scanned, first-order antenna beams. The line source is adapted to direct a predetermined one of these beams into the radiator.

摘要： A scanning array antenna employs a solid rotating core having an anisotropic refractive index within an apertured waveguide that emits radiation in response to an input beam propagating through the waveguide. Rotating the core changes its refractive index relative to the input beam, causing the radiated beams to undergo an angular scanning. The solid rotating waveguide core can be formed from a dispersion of aligned elongate conductive members in an isotropic dielectric, from a liquid crystal medium, or from a dispersion of aligned elongate conductive members in a liquid crystal medium. The antenna is operable in reciprocal transmission and reception modes.
