摘要： A non-squinting helical antenna is divided into segments separated by a coupler. This coupler is preferably a four port coupler which serves as a summation and difference power divider. Such a four port coupler allows the formation of a closed loop for controlling the steering angle of the antenna. The summation and difference signals between segments are monitored, and the ratio of these signals is used to determine and correct error in steering. The steering angle of the antenna can thus be maintained over a range of frequencies within a decibel of error.

摘要： A horizontally polarized end fire antenna array providing 360° scanning over a ground plane including a plurality of radiating cavity backed slots formed by a plurality of mutually separated flat, segments of metallization arranged in a grid and supported by a layer of dielectric material in a coplanar arrangement above and shorted to the ground plane. The side edges of the metallic segments define a plurality of substantially linear crossed slots running in at least two, e.g. orthogonal, directions. Each element of the array consists of four or more adjacent metallized segments having mutually opposing inner corners surrounding a common feed point. RF launch points for the array are formed across the slots of pairs of neighboring segments by conductor elements connected to respective common feed points. Two floating parasitic conducting elements are located in and around the area where the slots cross so as to make the array operate more effectively and comprise a crossed segment of metallization fabricated on the surface of the dielectric layer and a loop of metallization embedded in the center of the dielectric layer beneath the crossed segment.

摘要： A full coverage antenna module provides radiation in 360.degree. in a weight, space and cost effective manner. The antenna module includes two back-to-back electronically scanned (.+-.60.degree.) antenna arrays and an end-fire array mounted on at least one of a top surface and a bottom surface of the module. The end-fire array is bi-directional, may be scanned by .+-.30.degree. in both of its directions, and serves as a gap filler to provide coverage not supplied by the side arrays. The end-fire array may include a plurality of rows of antenna elements, adjacent rows of which are separated by an offset width. Preferably, the antenna elements in the rows have a non-periodic inter-element spacing. The antenna elements in the end-fire array may be of different types, for example, both monopoles and dipoles may be used in the same end-fire array. If monopoles are used, they are preferably mounted on a corrugated ground plane.

摘要： A quadrifilar helical antenna including four conductive helices having a common central axis, a common direction of turn about said axis, a common pitch, and a common length between opposite ends, the helices being uniformly spaced from each other by 90.degree., and a single dielectric helix concentric with the common axis, lying within and supporting the conductive helices at a nominal diameter. The dielectric helix has opposite ends, a plurality of turns having said common direction of turn, and a second pitch substantially greater than said common pitch. A casing contains the helices and is rotatably fixed to one end of the dielectric helix. A tuning device is fixed to the other end of the dielectric helix and rotatable relative to said casing, so that rotation of the tuning device twists the dielectric helix to alter the common pitch of the conductive helices without substantial variation from said nominal diameter.

摘要： An antenna comprising a ground plane having a base portion and a cylindrical obstruction that extends from the base. The obstruction is oriented such that its longitudinal axis is perpendicular to the base ground plane. The antenna also has a conducting transmission along the length of the exterior of the obstruction. A feedpoint located near the base ground plane transmits a voltage signal between the transmission element and the exterior of the obstruction. A short circuit is provided between the transmission element and the obstruction at a point distal to the feedpoint.

摘要： An efficiently radiating helical antenna includes a conductive helix receiving signals to be radiated at a first end of the conductive helix device for capacitively pulling fields generated by the signals towards a second end of the conductive helix opposite the first end. The device may be a conductive tube inserted into the second end of the conductive helix or a disjointed conductive helix surrounding the conductive helix. This scheme works especially well for a conductive helix having a circumference on the order of one wavelength.

摘要： A microwave buffer for use between transmitter modules and an impedance combiner. The buffer is comprised of a plurality of input segments, a plurality of output segments and an elongated transmission segment connecting the input segments to the output segments. The geometry of the buffer along with bridges located proximate to the transmitter modules eliminate the destructive effects of reflected waves set up by an unbalanced impedance combiner when one of the transmission modules becomes inoperative. The hourglass shape of the buffer causes the phases of the signals from each transmission module to be equal from any transmission port to any output. The bridges force the sum of the mutual couplings to be low in amplitude on any transmission module.

摘要： A radio frequency coupler connector includes a housing having first and second housing portions. The first housing portion includes a first open-ended launcher operatively connected to a first connection terminal, and the second housing portion includes a second open-ended launcher operatively connected to a second connection terminal. When the first and second housing portions are assembled, the first and second open-ended launchers are overlapped and separated by a dielectric, thereby providing a non-contact connection by capacitive coupling.
