  • Multiphase flow and salinity meter with dual opposite handed helical resonators
    Patent number: 11644351
    Abstract: A multiphase flow measurement apparatus includes a tubular, a first microwave resonator, a second microwave resonator, and a coplanar waveguide resonator. The tubular includes a wall formed to define an inner bore configured to flow a multiphase fluid. The first microwave resonator has a first helical shape with a first longitudinal length and is configured to generate a first electric field that rotates. The second microwave resonator has a second helical shape with a second longitudinal length different from the first longitudinal length of the first microwave resonator and is configured to generate a second electric field that rotates. The first and second microwave resonators are mutually orthogonal to each other and cooperatively configured to measure a salinity of the multiphase fluid flowing through the inner bore. The coplanar waveguide resonator is configured to generate a third electric field to measure a flow rate of the multiphase fluid.

  • MINIATURIZED, LOW POWER, WIRELESS TRANSMITTER AND RECEIVER WITH ON-CHIP ANTENNA, AND WIRELESS COUPLING OF ON-CHIP AND OFF-CHIP ANTENNA
    Publication number: 20100099367
    Abstract: A miniaturized, low power RF transmitter with a dual mode active on-chip antenna/inductor is disclosed in which antenna also serves as the oscillator inductor. Also disclosed is a miniaturized low power RF receiver with an on-chip antenna; and a RF transmitter system wherein an on-chip antenna is wirelessly coupled to an off chip patch antenna are disclosed. Advantageously, the TX chip is housed in a low loss, e.g. Low Temperature Co-fired Ceramic (LTCC) package with a patch antenna to provide a System-on-Package implementation comprising electromagnetic coupling between a RF TX chip comprising an integrated on-chip antenna and a package antenna.
