Patent application number | Title | Published |
20150314526 | METHOD AND APPARATUS FOR FOLDED ANTENNA COMPONENTS - Method and apparatus for making antennas and antenna components suitable for wideband transmission and reception are disclosed. Material accretion devices or apparatus such as a 3D printer can be used to form the antennas and antenna components. The antenna and antenna components can include folded and/or self-similar features. | 11-05-2015 |
20140090828 | Radiative Transfer and Power Control with Fractal Metamaterial and Plasmonics - Systems according to the present disclosure provide one or more surfaces that function as heat or power radiating surfaces for which at least a portion of the radiating surface includes or is composed of “fractal cells” placed sufficiently closed close together to one another so that a surface (plasmonic) wave causes near replication of current present in one fractal cell in an adjacent fractal cell. A fractal of such a fractal cell can be of any suitable fractal shape and may have two or more iterations. The fractal cells may lie on a flat or curved sheet or layer and be composed in layers for wide bandwidth or multibandwidth transmission. The area of a surface and its number of fractals determines the gain relative to a single fractal cell. The boundary edges of the surface may be terminated resistively so as to not degrade the cell performance at the edges. | 04-03-2014 |
20120319798 | WIDEBAND ELECTROMAGNETIC CLOAKING SYSTEMS - Arrangement of resonators in an aperiodic configurations are described, which can be used for electromagnetic cloaking of objects. The overall assembly of resonators, as structures, do not all repeat periodically and at least some of the resonators are spaced such that their phase centers are separated by more than a wavelength. The arrangements can include resonators of several different sizes and/or geometries arranged so that each size or geometry corresponds to a moderate or high “Q” response that resonates within a specific frequency range, and that arrangement within that specific grouping of akin elements is periodic in the overall structure. The relative spacing and arrangement of groupings can be defined by self similarity and origin symmetry. | 12-20-2012 |
20110095955 | FRACTAL ANTENNAS AND FRACTAL RESONATORS - An antenna includes at least one element whose physical shape is at least partially defined as a second or higher iteration deterministic fractal. The resultant fractal antenna does not rely upon an opening angle for performance, and may be fabricated as a dipole, a vertical, or a quad, among other configurations. The number of resonant frequencies for the fractal antenna increases with iteration number N and more such frequencies are present than in a prior art Euclidean antenna. Further, the resonant frequencies can include non-harmonically related frequencies. At the high frequencies associated with wireless and cellular telephone communications, a second or third iteration, preferably Minkowski fractal antenna is implemented on a printed circuit board that is small enough to fit within the telephone housing. | 04-28-2011 |
20110063189 | Methods and Apparatus for Enhanced Radiation Characteristics From Antennas and Related Components - Aspect of the present disclosure are directed to methods and apparatus producing enhanced radiation characteristics, e.g., wideband behavior, in or for antennas and related components by providing concentric sleeves, with air or dielectric material as a spacer, where the sleeves include one or more conductive layers, at least a portion of which includes fractal resonators closely spaced, in terms of wavelength. A further aspect of the present disclosure is directed to surfaces that include dual-use or multiple-use apertures. Such aperture engine surfaces can include a top (or first) layer of antenna arrays, a middle (or second) layer of a metal-fractal backplane player, and a third (or bottom) layer for solar cell or solar oriented power collection. | 03-17-2011 |

Further described are bondary condition layer structures that can activate and deactive cloaking/lensing structures. | 03-03-2011 |

Using fractal geometry, the antenna ground counterpoise has a self-similar structure resulting from the repetition of a design or motif (or “generator”) that is replicated using rotation, and/or translation, and/or scaling.
