Abstract
Among other things, one or more data-links for transferring information between a stationary unit and a movable (e.g., rotating) unit, or between two movable units without contact between the units is provided. A transmitting antenna of a data-link comprises at least two capacitive conducting portions, a first portion configured to conduct signals having a first frequency range (e.g., a higher frequency range) and a second portion configured to conduct signals having a second frequency range (e.g., a lower frequency range). The second portion is comprised of a plurality of members (e.g., conductive plates) arranged to create a substantially continuous electrically conductive structure (e.g., although respective members may not be in physical contact with adjacent members). In this way, a loss of capacitance in a transition between two adjacent members is reduced to provide for transferring information at lower frequencies where a higher capacitance is desirable, for example.
