Latest Patents

Vinoy holds a patent for "Miniaturized conformal wideband fractal antennas on high dielectric substrates and chiral layers." This invention represents a class of antennas that feature an electrically conductive fractal pattern on a dielectric substrate. These antennas are notably smaller, measuring in centimeters, compared to previous models that were measured in meters. The design includes two styles: one with a ground plane perpendicular to the substrate and another with a parallel ground plane. The substrate used has a dielectric constant ranging from about 10 to 600 or more, and it may include ferroelectric materials like barium strontium titanate. A bias voltage can be applied across the substrate to tune the antenna for specific frequency ranges. Additionally, the antenna can achieve wideband capabilities by incorporating an absorbing material behind the substrate. The fractal patterns utilized can include various designs such as the Hilbert curve, Koch curve, Sierpinski gasket, and Sierpinski carpet. One style of the antenna features a fractal pattern with multiple segments arranged in a specific configuration, which can be altered by a switch to achieve different configurations. The antenna elements may also be organized in a phased array.
