    Abstract: It is disclosed a waveguide array antenna for satellite communications. The antenna is configured to transmit and/or receive a first polarization signal and a second polarization signal, the second polarization being orthogonal to the first polarization, and comprises an array of unit cells, each comprising a radiating element. The antenna comprises: a grid configured to divide each radiating element into sub-elements having an inter-element distance lower than or equal to the wavelength at a highest frequency of operation of the antenna; and an electromagnetic band gap layer configured to support the grid above the radiating elements. The grid comprises a number of grid unit portions, and the electromagnetic band gap layer consists of a number of pins protruding from the walls of each grid unit portion.

    Abstract: The present invention relates to a novel lens antenna with a 3D near-field focus-steering capability that operates at gigahertz and terahertz frequencies. The novel antenna includes a pair of discrete dielectric lenses fed by a stationary horn source. In-plane synchronous counter-rotation and co-rotation of the lens pair steers its near-field focus radially and azimuthally, respectively, while linear translation of the upper lens moves the focal point longitudinally. The steering focus beam enables fast imaging. In imaging applications, the radiated beam from the novel lens antenna focused in the target area can reduce undesired interference from neighboring structures and increase the system dynamic range and signal-to-noise ratio.

    Abstract: A fill level sensor for detecting a level of a fill medium in a container includes a generator having a feed line, an antenna, a supply and a controller. The generator generates electromagnetic waves having a resonant frequency and outputs the electromagnetic waves via the feed line having a line impedance with a line impedance value. The supply is arranged between the feed line and the antenna and transmits the electromagnetic waves from the feed line to the antenna. The supply has a resonant circuit. The resonant circuit and the antenna together have a resonant input impedance in the transmission direction. The resonant circuit transforms the resonant input impedance at the resonant frequency into a real impedance having a predetermined resonant impedance value. The antenna has an antenna resonant frequency different from the resonant frequency.
