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.

Broadband conformal antenna

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.

Spherical dielectric lens side-lobe suppression implemented through reducing spherical aberration

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.

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.

A steerable antenna assembly ('SAA') for receiving a plurality of incident radio frequency ('RF') signals at a plurality of incident angles is disclosure. The SAA includes an approximately spherical dielectric lens (&#x201c;SDL&#x201d;), a waveguide aperture block (&#x201c;WAB&#x201d;), a switch aperture matrix (&#x201c;SAM&#x201d;), and a radial aperture combiner (&#x201c;RAC&#x201d;). The SDL receives and focuses the plurality of incident RF signals creating a plurality of focused RF signals at a plurality of focal points approximately along the back surface of the SDL. The WAB is positioned adjacent to the back surface of the SDL and receives the plurality of focused RF signals. The SAM electronically steers a beam of a radiation pattern produced by the SAA and switch between the pluralities of focused RF signals based on electronically steering the beam. The RAC produces a received RF signal from the plurality of focused RF signals.

A reconfigurable antenna comprises a plurality of antenna feed elements, a plurality of plasma switches respectively associated with the antenna feed elements, and control circuitry for independently operating the plasma switches to selectively activate and deactivate the antenna feed elements. Each plasma switch may comprise a volume of inert gas, and a pair of electrodes spanning the respective volume of inert gas. The reconfigurable antenna may comprise a power supply for supplying a voltage to the pair of electrodes of each of plasma switch sufficient to ignite the respective inert gas volume into a plasma field to deactivate the respective antenna feed element. Each plasma switch may optionally be operated to attenuate each antenna feed element.
