  • Patent number: 9577338
    Abstract: An antenna disposed on a substrate includes a radiating portion, a first coupling and feeding portion, and a second coupling and feeding portion. A length of the radiating portion is substantially equal to a half wavelength of electromagnetic signals radiated by the radiating portion. Each coupling and feeding portion includes a feeding part and a coupling part. The feeding part feeds the electromagnetic signals to the radiating portion via the coupling part so as to achieve effects of a multiple-input multiple-output (MIMO) antenna. A gap is defined between the coupling part and the radiating portion to improve an isolation of the MIMO antenna.

  • Patent number: 9537461
    Abstract: An antenna having a line feed delivering a radiofrequency (RF) signal to or from a radial waveguide is provided. The radial waveguide may include radiating elements on its periphery for converting the RF signal into a wireless signal. Filter elements are disposed within the waveguide, interposed radially between the line feed and the waveguide periphery. The filter elements are controllable for tunably filtering of the RF signal in their vicinity. Portions of the RF signal propagating through the waveguide in different direction may be bandpass filtered differently or blocked, thereby allowing for both beamsteering and bandpass filtering to support multiple frequency bands concurrently. Also provided is a design for the filter elements as tunable filter components of a frequency selective surface.

  • Patent number: 9083157
    Abstract: A collapsible, high voltage electrical discharge generator uses a set of telescoping winding sections to achieve a compact form suitable for efficient transport, storage and deployment. The winding sections have two typical arrangements, fully collapsed and fully extended. In the fully collapsed mode the sections can be telescoped together into a nested configuration, thus occupying a small fraction of the volume of a fully extended system. The towers can be erected into the fully extended mode by applying internal pressure, or alternatively by using mechanical linkage to simply extend the telescoped stack of winding sections into position. Fully extended and connected, the individual sections perform as a large, continuous inductive element capable of generating very high voltages at the top of the tower for use in testing equipment and producing long electrical discharges.
