摘要： A periodic metal array structure can be disposed between two antenna modules and include rows of metal unit assemblies that each includes metal units connected to each other in a longitudinal direction. Each metal unit has a first longitudinal strip, two first transverse strips, two second transverse strips, and two second longitudinal strips having shorter longitudinal lengths than that of the first longitudinal strip, and being respectively disposed on the left and right sides of the first longitudinal strip and respectively spaced apart therefrom by intervals at which the second transverse strips are located. The top and bottom ends of the first longitudinal strip are respectively connected with the first transverse strips. At least one first transverse strip can be connected to a first transverse strip of an adjacent metal unit. Each second transverse strip can be connected to the first longitudinal strip and a corresponding second longitudinal strip.

摘要： A controllable electrical outlet may comprise a resonant loop antenna. The resonant loop antenna may comprise a feed loop electrically coupled to a radio-frequency (RF) communication circuit and a main loop magnetically coupled to the feed loop. The controllable electrical outlet may comprise one or more electrical receptacles configured to receive a plug of a plug-in electrical load and may be configured to control power delivered to the plug-in electrical load in response to an RF signal received via the RF communication circuit. The RF performance of the controllable electrical outlet may be substantially immune to devices plugged into the receptacles (e.g., plugs, power supplies, etc.) due to the operation of the resonant loop antenna. For example, degradation of the RF performance of the controllable electrical outlet may be less when the controllable electrical outlet includes the resonant loop antenna rather than other types of antennas.

摘要： In the design of phased array antennas, as well as simple use of compact antennas, there is a strong interest to locate higher frequency antennas closer in spacing, and/or on the same surface, as the larger frequency antennas. What is needed is an array antenna technology, which can be conformal, and can interleave elements, as the frequency increases, to reduce array grating lobes. The desired solution would have much fewer required RF antenna ports, than the Tightly Coupled Dipole Antenna solutions. The optimal solution would also enable Dual or Diverse Polarization. This innovation embeds a wideband Slot Antenna, within the physical area of a larger electric dipole Antenna or Cross Dipole Antenna, with a De-Coupling gap around the Slot Ground Plane (or conductor) and isolates the Wideband Slot Antenna (the inner antenna) from the Dipole or Monopole antenna leg(s) (the Outer Antenna). Both (Inner and Outer) antennas have independent feeds and independent transmission line(s). Two key innovations are the use of a De-Coupling gap, and the use of the patent pending innovation “Compact Single Pole Wideband Slot Antenna Design with Inverted Co-Planar Waveguide Feed”. Both the Inner Slot Antenna and its CPW feed are independent and isolated from the Outer Antenna and its feed and transmission line. This structure, which could have a multiplicity of inner Slot Antennas with numerous RF ports, is very different from the slot or parasitic inner structure within a single port antenna system.

摘要： The disclosure relates to a fifth generation (5G) or pre-5G communication system supporting higher data rates after a fourth generation (4G) communication system such as Long Term Evolution (LTE). A module in a wireless communication system is provided. The module includes a plurality of antenna elements, an antenna substrate coupled to the plurality of antenna elements, a metal plate coupled to the antenna substrate, a calibration substrate coupled to a Radio Frequency (RF) component on a first face, and a conductive adhesive material for electrical coupling between the metal plate and the calibration substrate. The conductive adhesive material may be coupled to the calibration substrate on a second face different from the first face of the calibration substrate. The conductive adhesive material may include an air gap formed along a signal line included in the calibration substrate.

摘要： An embodiment an antenna unit of an antenna array includes a signal coupler, a phase-shifting modulator, and an antenna element. The signal coupler has a first input-output port, a second input-output port, and a coupled port. The phase-shifting modulator is coupled to the coupled port of the signal coupler, and the antenna element is coupled to the phase-shifting modulator via a connection remote from the signal coupler, or via an isolated port of the signal coupler. The phase-shifting modulator is configured for both relatively low signal loss and relatively low power consumption such that the antenna array can have significantly lower C-SWAP metrics than a conventional phased array while retaining the higher performance metrics of a conventional phased array.
