摘要： A satellite antenna arrangement for a satellite communication system comprising: a reflector for producing a far field pattern with near-zero field strength at a predetermined location to reject unwanted signals from said predetermined location or minimise signal power transmitted to said predetermined location, the reflector having a surface comprising a stepped profile arranged to generate the near-zero field strength in the predetermined location. The stepped profile may comprise a radial step. The location of the near-zero field strength can be steered by moving the reflector or by adjusting the amplitude and phase of an additional beam that covers substantially the same region as the main beam reflected by the reflector.

摘要： A substrate is provided with a multiplicity of electrically conductive elements, and the elements are interconnected to form an antenna structure for desired application. Either the antenna pattern itself may be altered according to the invention, or one or more feed points may be changed, or all of the above. As such, the electrically conductive elements may be interconnected to change the directionality of the antenna pattern, the gain, the frequency response, or other operational characteristics. The electrically conductive elements may be arranged in the form of an inchoate antenna pattern or regular array. Switches at key points of the structure enable the pattern to be changed dynamically. Such switching may be carried out in real time in accordance with transmissions/reception characteristics, or in advance using simulations associated with the switched elements.

摘要： The present invention relates to a beam steering system. The system includes an array of a plurality of antenna elements, each antenna element being electrically and mechanically controlled for steering a beam in a specific direction, and a millimeter wave subsystem quasi-optically integrated with a 3-dimensional beam steering device and an MMIC-type active circuit. The antenna element is controlled in real time by an electrical driving method so as to be moved in 2-dimensional space. That is, in the 3-dimensional system of the present invention, the beam is electrically controlled by a phase shifter, and each antenna element is physically moved by a mechanical driving mechanism. The 3-dimensional beam steering antenna and the associated devices are monolithically integrated on a substrate using MEMS technology, and the active circuit elements such as a mixer, a power amplifier (PA), a low noise amplifier (LNA), a VCO, etc. are integrated in an MMIC active array. The 3-dimensional beam steering device and the active MMIC circuit are integrated into one system by being interconnected using the quasi-optical technique. According to the present invention, shortcomings of the millimeter wave in that the SNR is low due to the low device output and high transmission loss in the free space can be overcome using the new RF transmission technique of 3-dimensional beam steering, and by introducing a micro antenna structure which is electrically and mechanically controlled such that wideband RF communication and 3-dimensional imaging is allowed in a Pico cell environment.

摘要： A circular polarization antenna whose radiation pattern is in the shape of a body of revolution about an axis and has a radiation minimum in the direction of this axis comprises a reflective conductive surface which is essentially in the shape of a body of revolution about the axis. A rectilinear conductive rod extends axially from a first end at the level of and isolated from the conductive surface to a second end and is connected at its first end to an excitation line. A plurality of radiating arms each have a first part extending in an essentially radial plane from the second end of the conductive rod. This first part is electrically connected at its proximal end direct to the conductive rod and is extended at its distal end by a curvilinear rod typically lying on the surface of a sphere centered at the second end and whose general direction is inclined relative to the radial plane.

摘要： A coplanar patch antenna is formed, e.g as a printed circuit, on a dielectric support (1) by a metal patch (2) spaced from a coplanar ground plane (3) by a peripheral slot (4), and in the improvement is series fed by means of a slot line (5). The slot (4) can be made resonant by having a periphery of one wavelength or an odd multiple thereof, and a second slot line (7) can be fed into the slot (4) at a distance of one or an odd multiple of a quarter wavelength from the slot line (5) to provide an independent feed. The arrangement presents a feedpoint impedance of about 50 ohms at the ports (6,8) instead of about 400 ohms in prior arrangements.Balancing loads or 180 degree hybrid feeds to other quadrature ports (11,12) can be used to correct beam asymmetry due to the slot line feeders (5 and 7).

摘要： A segmented phased array antenna system for scanning two different ranges of directions with a single set of antenna elements. The system comprises a plurality of segments (40), each of which has a plurality of antenna elements (48) mounted therein. The segments are mounted by support means (42, 44, 46) such that each segment is movable between first and second positions. In each set of positions, the antenna elements are operated as a conventional phased array radar system. The antenna system may be longitudinally mounted along the upper surface of the fuselage of an airplane (10) to provide side-looking radar coverage to both sides of the airplane.
