    摘要： Antenna module substrate employing vertical conductor loops for coupling noise reduction in radio-frequency (RF) transmission lines, and related antenna modules and fabrication methods. To provide effective electrical isolation between closely routed RF transmission lines in a metallization layer of the substrate, vertical conductor loops are formed in a metallization layer(s) adjacent to the RF transmission lines. The magnetic flux loop generated by the RF transmission lines as a result of carrying RF signals penetrates through the opening of the adjacent vertical loop structures, thereby inducing a magnetic field in the vertical conductor loops in the opposite direction of the magnetic flux. The induced magnetic field in the vertical conductor loops induces eddy currents in the vertical conductor loops, which in turn interferes with the magnetic flux thus causing a magnetic damping force in the magnetic flux, thus reducing or cancelling RF transmission line coupling noise.

    摘要： An apparatus is disclosed for implementing an antenna tuner. In an example aspect, the apparatus includes a substrate, an antenna disposed on or in the substrate, a radio-frequency integrated circuit disposed on the substrate, and an antenna tuner. The radio-frequency integrated circuit includes an amplification circuit. The antenna tuner is coupled between the antenna and the amplification circuit. The antenna tuner includes an inductive component disposed on or in the substrate and a capacitive component implemented within the radio-frequency integrated circuit.
