  • Patent number: 10581155
    Abstract: Antenna structures and methods of operating the same are described. One apparatus includes a processing device that executes an active interference cancellation (AIC) algorithm and radio frequency front-end (RFFE) circuitry coupled to the processing device. The RFFE circuitry includes two RF couplers, a fixed-delay filter, and an interference compensation circuit part of an electrical path between the two RF couplers. The AIC algorithm is operable to control the interference compensation circuit to adjust a phase, an amplitude or both of a copy of a first RF signal transmitted on a first antenna to remove corresponding interference in a second RF signal received at a second antenna that is caused by the first RF signal. The processing device triggers a re-calibration in the AIC algorithm when the digital values, received from a power detector circuit, indicate a change in impedance that exceeds a threshold.

  • Patent number: 10340594
    Abstract: The invention is directed to methods and systems for adjusting the vertical beam width of an imbalanced antenna. In one embodiment, first and second antenna arrays are imbalanced because one of the arrays has at least one more radiating element than the other. The additional gain created by additional radiating element(s) distorts the beam and alters the coverage area of the corresponding array, in embodiments. The tilt of the array having at least one more additional radiating element(s) is modified using phase shifting technology and based on the tilt of the array having fewer elements. By modifying tilt of the array having at least one more additional radiating element(s), the upper 3 dB points of the first and second array may be aligned to correct for the distorted beam and altered coverage area between the first and second arrays.

    Abstract: An antenna includes a stack of cylindrical lenses combined with feed elements to provide multi-beam coverage for a given wireless communication sector. Each cylindrical lens disc has approximately the same height as the feed elements being used with the lens. To overcome the problem of interference from cables and opposing feeds, feed elements are placed around the lens. The cylindrical lenses are stacked such that a small gap exists between each pair of adjacent cylindrical lenses, allowing for cable lines to pass through between the pair of the cylindrical lenses, and thus removing interference for 360 degree coverage. Cable lines are arranged such that they only traverse the portion of the circumferential surfaces of the cylindrical lenses that do not interfere with the field of view of the RF signals generated by the corresponding feed elements.

The linkage is preferably an expandable (e.g., flexural-scissor-grid) linkage capable of collapsing into a retracted/stowage state in which the MHA elements are maintained in a closely-spaced (e.g., hexagonal lattice close-packed) configuration optimized for payload storage. To deploy the antenna for operation, the linkage unfolds (expands) such that the MHA elements are moved away from each other and into an evenly spaced (e.g., wide-spaced hexagonal) pattern optimized for phased array operations. The MHA structures utilize modified helical filar elements including metal plated/printed on polymer/plastic beams/ribbons, or thin-walled metal tubes.

  • Patent number: 9641205
    Abstract: Antenna structures and methods of operating the same are described. One apparatus includes a processing device that executes an active interference cancellation (AIC) algorithm and radio frequency front-end (RFFE) circuitry coupled to the processing device. The RFFE circuitry includes two RF couplers, and a programmable-delay filter and a vector modulator disposed along electrical path. The AIC algorithm is operable to control the programmable-delay filter to match a delay of the electrical path to a propagation delay in an antenna path. The AIC algorithm is operable to control the vector modulator to adjust a phase, an amplitude or both of a copy of a first RF signal transmitted via the first antenna to generate a second RF signal. The second RF signal is added to a third RF signal via the second RF coupler to remove from the third RF signal interference caused by the first RF signal.

  • Patent number: 9369259
    Abstract: Methods and systems are disclosed for scalable antenna arrays that may be built up using pluggable tiles that have low distortion, flat band high gain, and structured to channelize the signals into narrow bands that may be 40 MHz or even smaller bandwidth apart. Antenna array tiles may employ traveling wave tube (TWT) components and wafer scale arrays. H-topology, equal length, feed networks connect the signals to antenna elements. The fractal-like, recursively repeating at different size scales, structure for the H-tree feed networks, implemented using pluggable tiles, facilitates the scalability of the high gain waveguide antenna array. System integration across the 75-115 GHz spectral band implements scalable aperture architecture with emphasis on addressing considerations of the TX power requirement, feed network, channelizing signals at different frequency bands using specially designed diplexers and combiners, cooling, component placement, and isolation.

  • Patent number: 9305888
    Abstract: Some embodiments relate to a semiconductor module having an integrated antenna structure that wirelessly transmits signals. The semiconductor module has a first die having a first far-back-end-of-the-line (FBEOL) metal layer with a ground plane connected to a ground terminal. A second die is stacked onto the first die and has a second FBEOL metal layer with an antenna exciting element that extends to a position that is vertically over the ground plane. One or more micro-bumps are vertically located between the first FBEOL metal layer and the second FBEOL metal layer. The one or more micro-bumps provide a radio frequency (RF) signal between the first FBEOL metal layer and the antenna exciting element of the second FBEOL metal layer. By using micro-bumps to connect the first and second die, the FBEOL metal layers are separated by a large spacing that provides for good performance of the integrated antenna structure.
