摘要： An antenna includes two radiators that are co-planar and exhibit mirror symmetry about an axis. Each radiator includes a half-Vivaldi sub-radiator bounded by a first curved edge and a first straight edge adjacent to the first curved edge. Each radiator also includes a curved monopole sub-radiator that is bounded by a second curved edge and a second straight edge adjacent to the second curved edge. The first and second straight edges coincide such that the first and second curved edges are continuous. When the antenna is driven at relatively high frequencies, the half-Vivaldi sub-radiators cooperate to act like a planar Vivaldi antenna. At lower frequencies, the curved monopole sub-radiators cooperate to act like a planar dipole antenna. Two of these antennas may be fabricated on circuit boards that intersect to form a dual-polarization antenna system.

摘要： An antenna feed for a stackable antenna system includes a polarization converter that continuously surrounds an omnidirectional antenna. Electromagnetic radiation emitted by the omnidirectional antenna and having an initial polarization passes through the first polarization converter, which converts the initial polarization into a non-vertical linear polarization. A feedline located outside of the first polarization converter forms a helix that wraps around the first polarization converter such that it runs perpendicularly to the non-vertical linear polarization. When the width of the feedline is sufficiently small, electrons in metal of the feedline will not be excited by the radiation, and the radiation will transmit through the feedline with minimal impact on the omnidirectional antenna's gain profile. The feedline may be used to feed a second antenna located vertically above the omnidirectional antenna. When the first polarization converter outputs horizontally polarized radiation, the feedline may form a straight vertical line.

摘要： A filtering power divider includes a first partial transmission line having a first electrical length, a second partial transmission line having a second electrical length, and a third partial transmission line having the second electrical length. The first, second, and third partial transmission lines connect to form a T-junction, and a sum of the first and second electrical lengths is ninety degrees. Thus, the first and second partial transmission lines cooperate to act as a quarter-wave transmission line. Similarly, the first and third partial transmission lines cooperate to act as a quarter-wave transmission line. Additional transmission lines may be connected to the first, second, and third partial transmission lines to implement a filter between an input port and each of two output ports.

摘要： A broadband antenna system is disclosed. The antenna system relates to a cylindrical structure, wherein the feed region comprises segmented radiators with tapered feed points, distributed around the circumference of the structure, and a balun that is co-planar with the cylindrical structure. This allows a plurality of feed lines, cables, piping, or other structures to be run through the center of the antenna without interfering with the performance of the antenna system. Segmentation of the radiators permits the integration of a corporate feed network, suppresses overmoding, and permits operation without the need for a ground plane. The invention further relates to a stacked broadband antenna system wherein additional antenna elements or devices may be stacked collinearly on the antenna structure and operated via the plurality of feed lines or other structures. The overall system thus provides a wide range of transmitting, receiving, sensing and other capabilities over a virtually infinite bandwidth.

摘要： A method for controlling an antenna array includes determining, based on a beamstate, an initial weight vector of excitations. The initial weight vector is transformed into an active-impedance vector. When the modulus of any element of the active-impedance vector exceeds a threshold, the initial weight vector is unsafe. In this case, a substitute weight vector is identified such that (i) the initial and substitute weight vectors have a similarity measure that exceeds a similarity threshold and (ii) the substitute weight vector is safe. The antenna array may then be driven according to the substitute weight vector to emit radiation having a radiation pattern that approximates that of the beamstate. The substitute weight vector may be found by searching a library of safe weight vectors or by adjusting the excitations of the initial weight vector until a safe alternative is found.

摘要： The present invention is directed to fuze system for munition that produces a height-of-burst (HOB) signal using two Global Positioning System (GPS) signals, the first signal being from a particular GPS satellite (the direct GPS signal) and the second signal being the GPS signal from the same GPS satellite after the signal has been reflected from the surface adjacent to the target. In one embodiment, the HOB signal is generated when there is a substantial correlation between the reflected GPS signal and direct GPS delayed by an amount of time that is indicative of the desired HOB.
