Abstract: A broadband conformal antenna (“BCA”) is disclosed. The BCA includes a narrow approximately rectangular outer conductive (“NARO”) housing, a plurality of dielectric layers within the NARO housing forming a laminated dielectric structure, and an inner conductor formed within the laminated dielectric structure. The NARO housing includes a top broad wall and the BCA further includes an antenna slot within the top broad wall. The BCA is configured to support a transverse electromagnetic signal within the NARO housing.

Abstract: A method to mitigate an antenna multipath, Rayleigh fading effect. The method includes coupling an antenna on top of a structure, wherein the structure is covered by a radio frequency (RF) radiation absorbing layer, wherein the structure has a shape such that any reflecting surface of the structure is perpendicular to an incoming RF signal. The method also includes directing the incoming RF signal towards the structure, wherein undesired direct or reflected RF signals are either absorbed by the RF radiation absorbing layer or deflected back to a source of the RF signal, thereby avoiding interference of the undesired RF signal with a desired RF signal aimed at the antenna.

Abstract: An antenna. The antenna includes a plurality of loop antennas sharing a common gap. The antenna also includes a nonlinear mixing component connected to the gap and configured to collect energy from at least one of the plurality of loop antennas.

Abstract: A method and apparatus for tuning a metamaterial cell. A set of electromagnetic properties of a tunable element associated with the metamaterial cell may be tuned. A resonance of the metamaterial cell may be adjusted in response to the set of electromagnetic properties being tuned. A range of frequencies over which the metamaterial cell provides a negative index of refraction may be changed in response to the resonance of the metamaterial cell changing.
