  • Patent number: 9825607
    Abstract: The present invention relates to a phase-shifting unit module, a manufacturing method therefor, a phase shifting device, and an antenna. The phase-shifting unit module comprises a first metal ground plate, a second metal ground plate, an insulating dielectric plate, a slide apparatus, and a fixed transmission line. The insulating dielectric plate is provided thereon with at least one impedance transforming part. The thickness of the impedance transforming part is less than the thickness of the remaining parts of the insulating dielectric plate. The impedance transforming part of the insulating dielectric plate is overlapped with the fixed transmission line during a moving process. The insulating dielectric plate is overlapped only with the fixed transmission line, thus reducing reflected signals, while at the same time reducing losses, and facilitating ultra-wideband design of the phase-shift unit module and of the phase-shifting device.

  • Patent number: 9742075
    Abstract: A hybrid active array approach can combine aspects of a passive and active array architecture with transmitter, high power, and cooling components positioned in one location, e.g., below a ship deck, apart from a radiating location. Waveguides or signal transmission lines can convey a transmit signal from the transmitter to the radiating location, e.g., to a beamforming network (BFN), hybrid transmit/receive modules (HTRM), and a plurality of antenna elements. The exemplary BFN can set an amplitude distribution of an antenna aperture associated with the BFN, HTRMs, and plurality of antenna elements to control both transmit and receive sidelobes where low or reduced sidelobes on transmit reduces radiation outside of the main beam further reducing signal returns in one or more sidelobes sections of the antenna elements. In a receive mode, a reverse can occur and additional beamformers can be utilized for beamforming the receive beams.

  • Patent number: 9568590
    Abstract: Methods and systems for thinning the output of an array antenna are disclosed. The thinning can be applied in response to determining that the performance of a multiple element antenna array with respect to a desired signal has been compromised by the presence of one or more interfering signals. The application of a thinning pattern has the effect of turning off selected antenna elements within the array. The effect of applying a particular thinning pattern on the realized performance of the antenna system can be determined. An alternate thinning pattern can be applied if the previous thinning pattern did not result in an improvement, or a sufficient improvement, in the performance of the antenna system.

  • Patent number: 9362609
    Abstract: A power amplifier uses a modular architecture in which each of the one or more modules spatially combines the power from multiple amplified channels. The individual modules are configured to operate in the EHF band and above at low loss. This entails reconfiguring the input and output splitters, the end-launched transitions between the amplifier chips and the input and output splitters and the packaging of the DC power and control board. The input splitter uses a split-block technology. The output splitter maps each amplified channel into a two-dimensional aperture.

  • Patent number: 8422947
    Abstract: A communication device includes a communication circuit part, a transmission path for signals, a ground, a coupler electrode, and a resonance part. The coupler electrode includes an upper flat part as an electrode, a support, and a connecting portion. The support supports the upper flat part. Thus, the upper flat part faces the ground and is separately placed therefrom at a height only enough to ignore the wavelength of the signal, while having a flexible portion which is elastically deformable in the height direction. On the connecting portion, the other end of the support is connected to the transmission path. The resonance part enlarges a current flowing into the coupler electrode through the transmission path. A micro dipole is a line segment connecting between the center of accumulated electric charge in the coupler electrode and the center of mirror charge accumulated in the ground.
