  • Patent number: 10141655
    Abstract: A multiport RF switch assembly with integrated impedance tuning capability is described that provides a single RFIC solution to switch between transmit and receive paths in a communication system. Dynamic tuning is integrated into each switch sub-assembly to provide the capability to impedance match antennas or other components connected to the multiport switch. The tuning function at the switch can be used to shape the antenna response to provide better filtering at the switch/RF front-end (RFFE) interface to allow for reduced filtering requirements in the RFFE. Memory is designed into the multiport switch assembly, allowing for a look-up table or other data to reside with the switch and tuning circuit. The resident memory will result in easier integration of the tunable switch assembly into communication systems.

  • Patent number: 10116050
    Abstract: One or more input signals are used to generate a Pseudo noise generator and re-inject the signal to obtain a more efficient method of control of a receiver using adaptive antenna array technology. The antenna array automatically adjusts its direction to the optimum using information obtained from the input signal by the receiving antenna elements. The input signals may be stored in memory for retrieval, comparison and then used to optimize reception. The difference between the outputs of the memorized signals and the reference signal is used as an error signal. One or multiple Modal antennas, where the Modal antenna is capable of generating several unique radiation patterns, can implement this optimization technique in a MIMO configuration.

  • Patent number: 10084233
    Abstract: A modal antenna array is described where modal antenna elements capable of generating multiple radiation modes are used to form array radiation patterns. Nulls in the array radiation pattern can be formed and positioned by proper modal antenna element mode selection, with these nulls used to provide interference suppression or mitigation. The shift in array radiation pattern maxima generated by modal element mode selection can be used to improve communication system link quality by optimizing array radiation pattern characteristics. Specifically, a ring or circular array configuration is described where a simplified common feed port can be implemented to feed multiple modal antenna elements used to form the array. A switch can be used to connect or disconnect one modal element from the array, with this feature providing additional unique array beam states. The modal array can be commanded via a look-up table or algorithm.

  • Patent number: 10051493
    Abstract: A network communication system includes three or more nodes that are wirelessly connected in a mesh configuration, forming a reconfigurable mesh network, to improve communication link performance. The reconfigurable mesh network can be dynamically adjusted to maintain and improve communication links throughout a region serviced by the mesh, or between a source and destination on the mesh network. Adaptive antenna system techniques are implemented in one or more of the nodes on the mesh network, such that multiple radiation pattern modes can be generated to dynamically adjust radiated performance between specific links along a selected path for communicating information on the mesh network. Antenna system metrics, such as signal to noise ratio, signal to interference plus noise ratio, and receive signal strength indicator are used to monitor and to adjust adaptive antenna system characteristics to optimize link performance between nodes on the mesh network.
