摘要： A process writes phase shift error correction values into a phased-array antenna to normalize a range of manufacturing variances. An axial ratio is determined for an antenna weight vector (AWV) by making multiple measurements with the horn of a test antenna mechanically rotating from 0 to 180 degree or with dual polarization test antenna. For calibration of the whole array, each subarray is treated in the same fashion as equivalent to an antenna element in the subarray calibration. The subarray is electronically rotated as a whole (all elements rotated by the same phase shift value) from 0 to 360 degree during the full array calibration. Due to small power variation among AWVs, calibration solely by REV results fail to consistently converge to resolution. Accordingly, the apparatus measures and compares axial ratios. During final fabrication, the apparatus programs an AWV with best axial ratio into each non-transitory array element.

摘要： An exemplary embodiment of an antenna in accordance with the present invention utilizes a sub-reflector and a main reflector with each of them having its own focal-ring type geometry. The antenna cooperates with a signal transmission feed disposed at the center of the antenna axis between the first and main reflectors to emit radio signals towards the sub-reflector. The sub-reflector reflects radio waves towards a main reflector which in turn reflects the radio waves to form the beam pattern emitted by the antenna. The reflecting surface of the sub-reflector is formed by a portion of an axially-displaced ellipse rotated about the antenna axis. The reflecting surface of the main reflector is defined by a section of a parabola rotated about the antenna axis to form a reflecting surface that concavely slopes away from the antenna axis. An embodiment of the antenna provides a wide coverage conical beam with selectable beam peaks that operate over a 2.25:1 frequency band range and provides substantially iso-flux beam density.

摘要： A single radiating structure with an integrated mode transducer that produces near-ideal radiation characteristics at two frequency bands. The dual band feed consists of three main sections: feed waveguide, mode transducer and corrugated horn. The feed waveguide consists of two concentric, circular waveguides that are excited in the TE.sub.11 coaxial and circular waveguide modes for the low and high bands, respectively. The mode transducer, which is critical to the performance of the feed, provides a single mode, low return loss transition, for both bands, between the feed waveguide and the corrugated horn. This is achieved by converting the TE.sub.11 circular waveguide modes into the fundamental hybrid, HE.sub.11, mode of the corrugated horn. The corrugated horn, which is a stepped-slot configuration, is designed to achieve a smooth transition from the mode transducer and to produce the desired radiation characteristics at both frequency bands.

摘要： The invention concerns a multimode feed for a reflector antenna of a monopulse tracking system. The feed comprises: a receiving element having an aperture, which receives an electromagnetic wave and generates, from the electromagnetic wave, a waveguide signal comprising a plurality of higher-order modes, as a function of an incidence angle of the electromagnetic wave on the aperture; and a waveguide structure, coupled to the receiving element, which generates, from the plurality of higher-order modes, a first error signal at a first output port and a second error signal at a second output port. The waveguide structure has: a first coupler that extracts, from the waveguide signal, a first higher-order mode and provides a first extracted signal; a second coupler that extracts, from the waveguide signal, a second higher-order mode and provides a second extracted signal; a third coupler that extracts, from the waveguide signal, a third higher-order mode and provides a third extracted signal; a fourth coupler that extracts, from the waveguide signal, a fourth higher-order mode and provides a fourth extracted signal; a first summing element that sums the first extracted signal and the second extracted signal, thereby generating the first error signal at the first output port; and a second summing element that sums the third extracted signal and the fourth extracted signal, thereby generating the second error signal at the second output port.

摘要： Disclosed herein is an omni-directional low distortion broadband coaxial horn antenna that supports a wireless bandwidth of 2-12 GHz with an instantaneous bandwidth up to 6 GHz wide within that 2-12 GHz range. These exemplary frequencies represent a single embodiment, but do not limit the range of possible frequencies the antenna can cover based on its design equations and scalability to other frequency ranges. In general, the antenna's dielectric shape is an hourglass cylindrical annulus with a curved conical void. The annular hole in the center of the antenna allows transmission line connection to the conductive surfaces applied to both the conical subtraction from the annulus and to the antenna's base. The present invention is not limited by this embodiment and also includes any embodiment of a cylindrical annulus with a conical void as determined in the manner disclosed herein and having conductive surfaces applied to it for electromagnetic radiation.
