Abstract: Techniques are provided for fabricating a low profile antenna that operates with increased efficiency. An antenna implementing the techniques according to an embodiment includes a first arm comprising a first spiral portion and a first rectilinear portion, and a second arm comprising a second spiral portion and a second rectilinear portion. The second spiral portion is concentric with the first spiral portion. The antenna further includes an insulator to separate the arms. The insulator and the arms are planar surfaces disposed within a rectangular region. The first rectilinear portion is adjacent to a first and second side of the perimeter of the rectangular region, and the second rectilinear portion is adjacent to a third and fourth side of the perimeter of the region. The antenna is fabricated as a printed circuit board which is mounted on the fuselage of an aircraft, which serves as a ground plane for the antenna.

Abstract: A Simultaneous Transmit and Receive (STaR) system utilizing high power transmitters and high sensitivity receivers in conjunction with one or more signal polarizers to maintain far-field polarization efficiency for both transmission and reception of same (or similar) frequency content at the same time. This STaR system maintains far-field polarization efficiency to remote target(s) while simultaneously introducing a near-field polarization mismatch between the transmission and receiver subsystems for higher isolation and reduced coupling.

Abstract: The system and method for a conformal millimeter wave (mmW) cavity backed slot antenna with near positive gain and hemispherical gain coverage. The antenna has a microstrip launch and feed and a surface mount connector. The mmW antenna may have a stripline launch or waveguide launch instead of a microstrip launch. In some cases, the microwave electronics can be mounted on the launch substrate instead of a connector.

Abstract: A cone antenna has at least one resistor electrically coupled to the radiating structure of the cone antenna. The capacitor may be part of a resistor network that is electrically connected to the cone. One or more patches may be coupled to the resistor network which act as a capacitor. A feed card may be embedded within a ground plane to enable the exterior of an antenna assembly to be conformal with an outer surface of a platform carrying the cone antenna.
