    Abstract: An ultra-wideband antenna device includes a radiation metal body, a first slotted hole, a second slotted hole, a third slotted hole, a fourth slotted hole, a ground point, and a feeding source. The radiation metal body includes a first side edge and a second side edge opposite to each other and a third side edge and a fourth side edge opposite to each other, the first slotted hole extends inward from the first side edge, the second slotted hole extends inward from the second side edge, the third slotted hole extends inward from the third side edge, and the fourth slotted hole extends inward from the fourth side edge. The ground point is located at a middle position of the radiation metal body, and the feeding source is located on the radiation metal body and away from the middle position.

    Abstract: The invention relates to a guide element for an antenna for a fill level meter, wherein the guide element is composed of a dielectric material and is used for forming, guiding and emitting electromagnetic radiation. The guide element has a permittivity course that changes over the spatial expansion of the guide element for specifically forming the electromagnetic radiation, the course being implemented by a spatial distribution of the material density of the dielectric material, wherein the material density is defined as one portion of dielectric material per elementary cell of a given size. Furthermore, the invention relates to a method for producing a guide element.

    Abstract: The present disclosure provides system and methods for optimizing the tuning of impedance elements associate with sub-wavelength antenna elements to attain target radiation and/or field patterns. Both static and variable (tunable) antenna systems may be manufactured. Static embodiments may be entirely passive in some embodiments. A scattering matrix (S-Matrix) of field amplitudes for each of a plurality of modeled lumped ports, N, may be determined that includes a plurality of lumped antenna ports, Na, with impedance values corresponding to the impedance values of associated impedance elements and at least one modeled external port, Ne, located external to the antenna system at a specified radius vector. Impedance values may be identified through an optimization process, and the impedance elements may be tuned (dynamically or statically) to attain a specific target radiation pattern.

    Abstract: Disclosed is a Cassegrain microwave antenna, which comprises a radiation source, a first metamaterial panel used for radiating an electromagnetic wave emitted by the radiation source, and a second metamaterial panel having an electromagnetic wave convergence feature and used for converting into plane wave the electromagnetic wave radiated by the first metamaterial panel. Employment of the principle of metamaterial for manufacturing the antenna allows the antenna to break away from restrictions of conventional concave lens shape, convex lens shape, and parabolic shape, thereby allowing the shape of the Cassegrain microwave antenna to be panel-shaped or any shape as desired, while allowing for reduced thickness, reduced size, and facilitated processing and manufacturing, thus providing beneficial effects of reduced costs and improved gain effect.
