Systems and methods are provided for providing vibration transduction and radio-frequency communication in proximity to an electrically conductive structure. The system may comprise an antenna element, an electrically conductive structure in proximity to the antenna element, and a vibration transducer comprising a material. The material may comprise a ferromagnetic material with piezoelectric properties. The vibration transducer may be positioned between the antenna element and the conductive structure.

System and method for monitoring material change by measuring at least one metric. In a first configuration, an EM signal is transmitted across a calibrated transmission configuration to at least one load including the material, the reflection is measured, and the at least one metric is calculated based at least on the reflection. In a second configuration, an EM signal is transmitted in the vicinity of at least one resonator that is operably coupled with a load that can include the material. An EM signal is received that has been affected by the resonator, and a measurement of the at least one metric can be based at least on the received signal.

In some embodiments, a radio frequency identification (RFID) system may include at least one Ultra High Frequency (UHF) antenna component, a conductive loop having a largest dimension that is smaller than the wavelength of radiation transmitted at a Microwave Frequency (MW). The conductive loop may define a gap and an RFID chip may be electrically coupled to the conductive loop. The conductive loop may be configured to be resonant at an Ultra High Frequency (UHF) and less resonant at Microwave Frequency (MW). The antenna component may be selected from the group consisting of a dipole antenna, a monopole antenna, a loop antenna, or a slot antenna.

An electronic device may include a substrate and a conductive layer on the substrate. The conductive layer may be patterned to form a first region and a second region that surrounds and defines the shape of the first region. The first region may be formed from a continuous portion of the conductive layer. The second region may include a grid of openings that divides the conductive layer into an array of patches. The first region may form an antenna resonating element for an antenna. The second region may block antenna currents from the antenna resonating element and may be transparent to radio-frequency electromagnetic waves. The openings may have a width that is too narrow to be discerned by the human eye. This may configure the first and second regions to appear as a single continuous conductive layer despite the fact that an antenna resonating element is formed therein.
