Samsung patents resonator design using internal metal holes for better signal control
This filing describes a resonator, a component that stores and directs electromagnetic energy, made of a non-conductive material wrapped in metal. It features a specific internal hole lined with metal that aligns with the natural flow of the electric field to help waves bounce effectively inside the device.
In the filing’s own words
A dielectric waveguide resonator includes: a dielectric resonant cavity including a dielectric body and a metal plating layer wrapping an outer surface of the dielectric body; and a metal interface provided in the dielectric body and connected to the metal plating layer, where the metal interface intersects a direction of an intrinsic electric field of the dielectric resonant cavity. The dielectric waveguide resonator includes a blind hole recessed inwards from a surface of the dielectric body, where a bottom surface of the blind hole includes the metal interface, and where an axial direction of the blind hole corresponds with the direction of the intrinsic electric field of the dielectric resonant cavity.
What exactly they claim (claim 1)
1. A dielectric waveguide resonator, comprising: a dielectric resonant cavity comprising a dielectric body and a metal plating layer wrapping an outer surface of the dielectric body; a blind hole recessed inwards from the outer surface of the dielectric body; and a metal interface included in a surface of the blind hole and connected to the metal plating layer, wherein the metal interface intersects a direction of an intrinsic electric field of the dielectric resonant cavity, and wherein the metal interface is located at a position at which a dominant mode of the dielectric resonant cavity is strongest, such that electromagnetic waves in the dielectric resonant cavity oscillate between the metal interface and a first surface of the dielectric body.
