Abstract: A low profile, broadband radiator operates as a dielectric rod antenna (DRA) but is conformally mounted to a conducting sheet along its axis of symmetry. The new device exploits the imaging theory of electromagnetics to split the DRA in half while maintaining its full-height TEM feed, HE11 waveguide, and radiation taper characteristics. The disclosed device is attractive for applications requiring directed energy on or near the axis of the antenna, i.e. ‘end-fire’, and for high shock and velocity environments. Bandwidth extension is realized by adding one or more cores of higher dielectric material and by modifying the feed and mode formation regions. A second polarization is generated by configuring the feed for odd-mode transmission and creating a flared notch radiator within a metallized split launcher.

Abstract: A MMIC amplifier is directly connected to the balanced feed points at the aperture of an antenna to eliminate the distance between electronics coupled to the antenna and the antenna itself, such that interfaces, components and connection lines which introduce losses and parasitic effects that degrade system performance are eliminated due the direct connection. Expanding the aperture of the antenna to accommodate the direct connection of a MMIC amplifier to balanced feed points of an antenna has been found to have no deleterious effects on antenna performance. Moreover, when coupling the MMIC amplifier to an unbalanced coaxial line, any associated ripple is minimized due to the direct connection.

Abstract: The system and method for chromatic correlation interferometry direction finding (CIDF) used to resolve ambiguities. Ambiguities are overcome by correlating over a range of frequencies. In some cases, multiple (i.e., 2 or more) frequencies or a continuous range of frequencies are used to make a more robust correlation manifold. As the complex response manifold is frequency dependent, using a set of two or more manifolds provides a significant reduction of false peaks.
