摘要： A multiple-beam antenna system includes at least one reflector and a cluster of horns for feeding the reflector. A horn of the cluster of horns is configured for providing transmission and reception of signals over respective transmission and reception frequency bands. The horn includes a substantially conical wall having an internal surface with a variable slope. The internal surface of the substantially conical wall includes slope discontinuities. At least one of the slope discontinuities has a diameter greater than 1.7 times the wavelength of the lowest frequency of the transmission frequency band. The diameter is also greater than 1.7 times the wavelength of the highest frequency of the transmission frequency band. In addition, the diameter is greater than 1.7 times the wavelength of the lowest frequency of the reception frequency band, and the diameter is greater than 1.7 times the wavelength of the highest frequency of the reception frequency band. This configuration of the slope discontinuity generates one or more higher order modes of a transverse electric (TE) mode over the transmission and reception frequency bands without generating a transverse magnetic (TM) mode.

摘要： A radio wave receiving converter is provided with a circular waveguide unit to which a vertically-polarized wave and a horizontally-polarized wave are input, first and second board holding units provided on the upside and the downside of the circular waveguide unit and holding first and second circuit boards, respectively, and first and second feed probes having tip portions provided to protrude into a waveguide element in parallel with the vertically-polarized wave and the horizontally-polarized wave, respectively, and having proximal end portions connected to the first and second circuit boards, respectively. Accordingly, the first and second board holding units are provided on the upside and the downside of the circular waveguide unit, and thus there is no need to use a sliding insert in the design of a die, so that the die can easily be fabricated at low cost.

摘要： A phased array antenna system on an aircraft that incorporates a choke plate that significantly attenuates sidelobes of the antenna beam pattern at elevation angles that would cause RF interference with ground-based terrestrial wireless networks. The choke plate includes a plurality of choke grooves that substantially circumscribe the antenna aperture. The choke plate has an upper surface that is positioned generally coplanar with the upper surface of the antenna aperture. The grooves of the choke plate may be filled with a dielectric material. The choke plate provides a smooth aerodynamic component that significantly attenuates beam scattering, and thus the radiation pattern sidelobes of the antenna at or below the horizon, when the aircraft is in flight.

摘要： A multibeam primary radiator apparatus (2) includes first, second and third primary horns (16, 18, 20). The first primary horn (16) has a generally circular proximal end aperture (22) at its proximal end, and a generally circular distal end aperture (24) at its distal end, which is larger than the proximal end aperture (22). The second and third primary horns (18, 20) have generally circular proximal end apertures (26, 28) at their proximal ends, and larger distal end apertures (30, 32) at their distal ends. The first through third primary horns are disposed with the center axes of the respective proximal end apertures being substantially in parallel with each other. The distance between the center axis of the first primary horn (16) and each of the second and third primary horns (18, 20) is smaller than the diameter of the proximal end aperture (22) of the first primary horn (16). The distal end aperture (30, 32) of each of the second and third primary horns (18, 20) is formed by a semicircular portion (30a, 32a), which is half of a circle having a diameter larger than the proximal end aperture (26, 28), on the side remote from the first primary horn (16), and also a semi-elliptical portion (30b, 32b), which is half of an ellipse, on the side closer to the first primary horn (16). Each semi-elliptical portion (30b, 32b) is contiguous to the associated semicircular portion (30a, 32a) at the two ends of the major axis thereof, and is located in a void in the distal end aperture (24) of the first primary horn (16). The end of the minor axis of each ellipse is located outward of the proximal end aperture (22) of the first primary horn (16).

摘要： Method and apparatus for feeding a compact main reflector of an RF antenna on a plurality of spectrally offset frequency bands. The method can include the steps of forming a focal ring for a main reflector (304) by positioning an RF source (301) at a first frequency within a first frequency band in the far field relative to a shaped non-linear surface of revolution so that the shaped non-linear surface of revolution forms a subreflector (302). A second focal ring can be formed for the main reflector (304) by positioning a second RF source (300) in the nearfield of the shaped non-linear surface of revolution.
