摘要： An antenna system includes an antenna element and an electromagnetic bandgap element proximate the antenna element wherein the electromagnetic bandgap element is optimized for narrow bandwidth operation thereby providing radiofrequency selectivity to the antenna system. Preferably the electromagnetic bandgap element is tunable such as through use of a bias-alterable dielectric substrate or other tuning mechanism. The design approach also provides a means of creating an ultra-thin low-profile narrowband tunable channel selective antenna system suitable for low frequency applications.

摘要： An antenna array comprised of a fractile array having a plurality of antenna elements uniformly distributed along a Peano-Gosper curve. An antenna array comprised of an array having an irregular boundary contour comprising a plane tiled by a plurality of fractiles covering the plane without any gaps or overlaps. A method for generating an antenna array having improved broadband performance wherein a plane is tiled with a plurality of non-uniform shaped unit cells or an antenna array, the non-uniform shaped and tiling of the unit cells are then optimized. A method for rapidly forming a radiation pattern of a fractile array employing a pattern multiplication for fractile arrays wherein a product formulation is derived for the radiation pattern of a fractile array for a desired stage of growth. The pattern multiplication is recursively applied to construct higher order fractile array forming an antenna array.

摘要： An optimal configuration for at least one antenna and/or at least one frequency selective surface is generated. A configuration of elements is generated by selecting a simple configuration of at least one element and applying a genetic algorithm to the simple configuration to generate a configuration optimized for various characteristics. A stochastic process may be used to randomly select an arrangement of elements as the simple antenna configuration and to select elements that connect the randomly selected elements to produce a stochastic configuration to which the genetic algorithm is then applied. Alternatively, an iterated or semi-iterated process may be applied to the simple antenna configuration to produce a fractal or a semi-fractal configuration, respectively, to which the genetic algorithm is then applied. Also, the elements may be optimized independently.
