The dielectric antenna that is easy to produce, has little interference and has a short construction as a result of the dielectric antenna having essentially the cross section of the radiation opening in the area of the supply section.

    Abstract: Methods for assembling an active array system are described. In one exemplary embodiment, an active subarray panel assembly having a first surface with a first array of electrical contacts and a radiator aperture with an array of radiator structures and an aperture mounting surface with a second array of electrical contacts are assembled together. The first surface of the panel assembly and the aperture mounting surface of the radiator aperture are brought into contact with an adhesive layer including microwave interconnects in a pattern corresponding to the first array of electrical contacts and the second array of electrical contacts so that the adhesive layer is between the first surface of the panel assembly and the aperture mounting surface of the radiator aperture. Pressure, heat and vacuum are applied to cure the adhesive and complete engagement of the microwave interconnects.

  • Publication number: 20120068890
    Abstract: In some developing interconnect technologies, such as chip-to-chip optical interconnect or metal waveguide interconnects, misalignment can be a serious issue. Here, however, a interconnect that uses an on-chip directional antenna (which operates in the sub-millimeter range) to form a radio frequency (RF) interconnect through a dielectric waveguide is provided. This system allows for misalignment while providing the increased communication bandwidth.

  • Publication number: 20120056794
    Abstract: A waveguide includes a dielectric substrate having first and second opposed surfaces defining a longitudinal wave propagation path therebetween; and a conductive grid on the first surface of the substrate and comprising a plurality of substantially parallel metal strips, each defining an axis. The grid renders the first surface of the substrate opaque to a longitudinal electromagnetic wave propagating along the longitudinal wave propagation path and polarized in a direction substantially parallel to the axes of the strips. The grid allows the first surface of the substrate to be transparent to a transverse electromagnetic wave having a transverse propagation path that intersects the first and second surfaces of the substrate and having a polarization in a direction substantially normal to the plurality of metal strips. A diffraction grating on the second surface allows the waveguide to function as an antenna element that may be employed in a beam-steering antenna system.

  • Patent number: 8077094
    Abstract: A plasma device having low thermal noise, which results in a high signal-to-noise ratio (SNR) of the plasma device. The plasma device includes devices with a plasma that is responsive to electromagnetic radiation and/or electrical signals. In various configurations, the plasma device has a plasma in which the temperature, resistance, pressure, and/or collision frequency are at a level sufficiently low to produce an acceptable level of noise. In another configuration, the operating frequency of the plasma device is at a level sufficiently high to produce an acceptable level of noise. Decreasing the noise level results in increasing the signal-to-noise ratio and increasing the data rate. The plasma temperature is reduced by operating the plasma device in the afterglow state. The plasma electron temperature is reduced by confining high energy electrons in a potential well and by using an electron emitting filament.

    Abstract: A plurality of conductive strip elements compose multilayer loading structures on top and bottom surfaces of a dielectric transmission substrate, by which a part of intra-substrate transmission components of a electromagnetic wave are leaked out of the surfaces. Each multilayer loading structure includes a first conductive strip group of conductive strip elements within a first plane, and a second conductive strip group of conductive strip elements within a second plane, and the first and second conductive strip groups are formed to be capacitively coupled to each other. In each of the first and second conductive strip groups, the conductive strip elements are placed at intervals of a distance of a quarter or less of a reference adjacent distance, where the reference adjacent distance is defined as a distance for generating spatial harmonics of the electromagnetic wave on the surfaces of the dielectric transmission substrate.

  • Publication number: 20110122036
    Abstract: Provided is a circuit for an electronic device having a non-planar transparent resonator. The transparent resonator is mounted on said circuit so as to at least partially occupy a footprint of another component of the circuit. The transparent resonator forms part of a light pathway on said circuit for transmitting light to or from said another component. Also provided is a transparent dielectric resonator antenna (DRA) for optical applications. Since the DRA is transparent, it can let light pass through itself and, thus, the light can be utilized by an optical part of a system or device. The transparent DRA can be placed on top of a solar cell. Since the DRA does not block the light, the light can reach the solar cell panel and power can be generated for the system or device. The system or device so obtained is very compact because no extra footprint is needed within the system or device for the DRA. It finds application in compact wireless applications that need a self-sustaining power device.
