摘要： A dual-polarization wireless base station antenna that implements vertical electrical downtilt and sidelobe reduction using beam steering circuit that includes a variable power divider and a multi-beam beam forming network. The variable power divider includes a single adjustable control element to divide an input voltage signal into a pair of complimentary amplitude voltage drive signals that exhibit matched phase and constant phase delay through the variable power divider. The beam forming network is configured as a double-sided, edge-connected microstrip module mounted to a main panel, which support the antenna elements in a vertical column organized into sub-arrays in a manner that implements sidelobe reduction. The power distribution network connecting the beam steering network to the antenna elements implements beam tilt bias and sidelobe reduction through coordinated phase shifting implemented through transmission media trace length adjustment.

摘要： An improved waveguide circulator that eliminates the need for quarter-wave dielectric transformers or impedance steps in the interface waveguide for broadband operation is described. The circulator designs in the prior art all require impedance matching elements outside of the ferrite element in order to achieve acceptable performance. Through the use of this new invention, broadband circulator performance can be achieved without the addition of impedance matching elements in order to minimize the cost, size, mass, and loss of the circulator.

摘要： A wiper-type phase shifter with a cantilever shoe that ensures that the electrical contact on the wiper arm remains in electrical communication with the transmission trace located on the antenna backplane without relying to an element, such as a spring-loaded set screw, that passes through the backplane. The cantilever shoe thus provides a wiper hold-down mechanism without requiring holes or slots through the backplane, which could allow rain or other elements to get inside the antenna enclosure. A dual-polarization antenna that includes a wiper-type phase shifter for each polarization. The wiper arms define gear portions that engage each other, which allows a single actuator, typically located on the rear of the backplane opposite the location of the wiper arms, to drive both wiper arms in a coordinated manner. The antenna is suitable for use as a wireless base station antenna.

摘要： An antenna comprising a feed (42) for delivering electromagnetic energy to a rotatable combination of a dielectric lens (44) and a reflective surface (46). The combination of the dielectric lens and the reflective surface is placed proximate to and in front of an energy feed, such as a horn (42), to support the scanning of an antenna beam in response to rotation of the lens/reflective surface assembly. The lens typically comprises a dielectric material and the reflective surface can comprise a thin layer of material operable to reflect electromagnetic energy. For example, the lens can comprise a half-cylinder shape of dielectric material and the reflective surface can be applied to the flat portion of the half-cylindrical lens. Alternatively, the antenna can comprise two or more electromagnetic feeds (72a, 72b, 72c, 72d) and a cylindrical lens of dielectric material including a centrally embedded, two-sided reflective surface. A positioning system can be used to rotate the combination of the lens and the reflective material proximate to and in front of the electromagnetic feed(s).

摘要： A phased array antenna system operative to broadcast multiple beams that each include coded data for specific users located within the coverage area of the corresponding beam. An appropriate receiver then receives and decodes a particular beam to extract the specific data for a corresponding user. Multiple users may be assigned to each beam using frequency division or orthogonal code multiplexing, and the user data may be encoded into the beams using frequency shift key or phase shift key encoding. For each coding technique, the encoded antenna control signals are combined into a total gain and total phase shift control signal, which drives a single phase and gain control device for each antenna element. In addition, a single data modulator generates the coding parameters for the entire communication system.

摘要： Using a method and apparatus for connecting an electrical cable (3) to a circuit board (5). The connector (400) is largely semi-circular in shape and generally comprises four prongs (450) for attaching the connector (400) to the edge of a circuit board (5). The connector (400) is particularly useful for attaching a coaxial cable (3) to a circuit board (5) where the coaxial cable (3) is not very flexible. The coaxial cable (3) can be easily placed onto the connector (400). Once the coaxial cable (3) is placed on the connector (400), the outer conductor (7) can be attached to the connector (400) and the inner conductor (8) can be attached to the circuit board (5).

摘要： A spot beam satellite communications system and method for delivering information to user terminals at a high data rate. In a hub, a high data rate serial data stream is separated into parallel data streams that are modulated onto respective uplink transponders. The uplink transponders are transmitted by the hub to an earth-orbiting satellite, which translates the uplink signals to downlink frequencies. The satellite broadcasts the transponders to user terminals located in the desired beam coverage areas on the earth. The user terminal separates the downlink transponders and demodulates each of the downlink transponder signals to regenerate the parallel data streams. The parallel data streams are combined to reproduce the original serial data stream. By dedicating multiple transponders to a particular data stream, data can be relayed at a very high data rate by a communications satellite that employs a standard transponder frequency assignment scheme.

摘要： A ferrite scanning line source (100) is formed of a ferrite toroid (102) and one or more dielectric slabs (105, 106) mounted to a side of the toroid (102). A signal propagating through the waveguide is phase shifted by the magnetization of the toroid (102). The further down the toroid the signal propagrates the greater the phase shift that is applied to the signal. Radiators or coupling ports are formed by slots (112) cut in a wall (116) of the waveguide. The phase of the signal radiating from each slot (112) in the line source (100) is shifted from the signal emanating from the preceding and following slot in the line source (100). By properly locating the slots (112) along the line source (100), a composite beam formed by the energy radiating from each slot may be titled to a desired direction.
