Abstract: 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.

Abstract: An antenna system includes: a patch antenna element disposed at a first level of the antenna system; an energy coupler configured and coupled to the patch antenna element to transfer energy between the patch antenna element and a front-end circuit; a ground conductor disposed at a second level of the antenna system, the patch antenna element and the ground conductor being disposed a separation distance away from each other and bounding respective sides of a volume defined by a projection, normal to a surface of the patch antenna element, of the patch antenna element to the ground conductor; and a floating conductor that is displaced from the ground conductor and the patch antenna element, the floating conductor comprising a body extending over a portion of the separation distance outside of, and in close proximity to, the volume.
