  • Patent number: 11962095
    Abstract: Disclosed is a high frequency radiator for an antenna. The high frequency radiator is formed of two interlocking PCB stems on which a radiator plate is mounted. Disposed on each of the interlocking PCB stems are two combinations of a feeder metallic trace and an opposing metallic trace, disposed on opposite sides of the PCB stem and electrically coupled together by at least one via formed in the PCB stem and a solder point within the via. This configuration of high frequency radiator is considerably cheaper to manufacture compared to conventional designs and is less susceptible to impedance matching problems resulting from inconsistent solder joint dimensions.

  • Patent number: 11933599
    Abstract: Disclosed is an electronic device. The electronic device comprises: a first image sensor and a second image sensor; and a processor which alternately performs a first image capture mode, in which a plurality of captured images are acquired by controlling the respective exposure times of the first image sensor and the second image sensor differently, and a second imager capture mode, in which a plurality of captured images are acquired by controlling the respective exposure times of the first image sensor and the second image sensor identically, identifies an object by using the plurality of captured images acquired in the first image capture mode, and acquires distance information about the identified object on the basis of the plurality of captured images acquired in the second image capture mode.

  • Publication number: 20230411868
    Abstract: Disclosed is an antenna having a plurality of radiator columns and an integrated phase shifter/calibration board. The radiator columns have radiator clusters that may be differentially phase to provide beam tilt. The input traces of each of the phase shifters is capacitively coupled to a Wilkinson power divider that sums the power of all the input signals, thereby providing a calibration function. The output traces of each of the phase shifters has a designated meander pattern that provides phase alignment for all the output signals to prevent phase mismatches between signals fed to the radiator clusters.

  • Publication number: 20230352831
    Abstract: An 8T8R antenna has a plurality of columns of antenna elements whereby a subset of the columns are combined into a plurality of composite columns. In an example, the antenna has six columns of antenna elements whereby the two columns at either end of the array are combined into a composite column. The antenna ports corresponding to the two outer composite columns are coupled to a splitter/combiner that has a power divider and a delay line to provide phase compensation. The antenna also has a phase compensator that provides for phase compensation between the outputs of the splitter/combiners and the antenna ports corresponding to the inner columns that are not combined into composite columns. In a variation, the columns of antenna elements are combined into a plurality of composite columns, each having a pair of columns, whereby the number of columns is twice the number of composite columns.

  • Patent number: 11804662
    Abstract: A telecommunications antenna comprising a plurality of unit cells each including at least one radiator which transmits RF energy within a bandwidth range which is a multiple of another radiator. The radiators are proximal to each other such that a resonant condition may be induced into the at least one radiator upon activation of the other radiator. At least one of the radiators is segmented into capacitively-connected radiator elements to suppress a resonance response therein upon activation of the other of the radiator.

  • Patent number: 11450956
    Abstract: Disclosed is an antenna phase shifter that comprises an outer conductive trace, an inner conductive trace, a wiper arm having a pivot point, and a capacitive coupler that capacitively couples an input port to the wiper arm conductive trace and capacitively couples the input port to a phase reference port. The capacitive coupler provided DC blocking between the input port and the phase reference port, and the input port may be coupled to a Bias-T such that the DC component present at the input port may be coupled to the Bias-T to drive the phase shifter wiper arm motor. In addition, the capacitive coupler provided constant capacitance while the wiper arm rotates.

  • Patent number: 11431105
    Abstract: Disclosed is a telecommunications antenna having a plurality of cloaked low band (LB) and high band (HB) dipoles. The LB and HB dipoles provide cloaking by breaking the dipoles into dipole segments, and providing conductive cloaking elements over the gaps between dipole segments to form a plurality of capacitors along the dipole. The capacitors along the LB dipoles provide a low impedance to LB RF signals and a high impedance to HB signals. The capacitors formed on the HB dipoles provide a low impedance to RF signals and high impedance to harmonics of the LB RF signals. This cross-cloaking of dipoles enables more dense arrangements of LB and HB dipoles on an antenna array face, providing opportunities to arrange, for example, the LB dipoles with an array factor that results in an advantageous fast roll off gain pattern.

  • Patent number: 11283195
    Abstract: A multiband antenna has a plurality of first, unit cells and second unit cells. Each first unit cell has two high band radiator clusters and two low band radiators disposed approximately in the center of each of the high band radiator clusters. Each second unit cell has two high band radiator clusters and one low band radiator that is disposed between the two high band radiator clusters. The first unit cell is designed for a superior low band gain pattern, and the second unit cell is designed for a superior high band gain pattern. By selectively arranging the first and second unit cells in a specific heterogeneous pattern, the characteristics of the two unit cells may advantageously and constructively combine to form a high performance antenna gain pattern that is consistent across the low band and high band.

  • Patent number: 11217358
    Abstract: Optically transparent, highly conductive conductor materials are provided, which in certain variations may also be flexible. Methods of making transparent conductive conductors, such as electrodes, are also provided. Such a method may include creating a groove pattern on a substrate that defines a two-dimensional array. Then an electrically conductive material may be selectively applied within the groove pattern of the substrate so as to create a transparent conductor (e.g., a transparent conductive electrode (TCE)). The transparent conductor has a sheet resistance of ?about 5 Ohms/Square and a transmissivity of ?about 50% for a predetermined range of target wavelengths of electromagnetic energy. Such methods may form linear micromesh conductive arrays and tortuous micromesh conductive arrays that can be used in a variety of optoelectronic applications, including as optically transparent, flexible and mechanically reconfigurable zeroth-order resonant (ZOR) antennas.
