  • CIRCUIT SUBSTRATE, ANTENNA ELEMENT, BUILT-IN MILLIMETER WAVE ABSORBER FOR CIRCUIT SUBSTRATE, AND METHOD FOR REDUCING NOISE IN CIRCUIT SUBSTRATE
    Publication number: 20210367351
    Abstract: A circuit substrate includes a multi-layer substrate in which a plurality of dielectric layers are stacked, and a millimeter wave absorber provided inside the multi-layer substrate and having an electromagnetic wave absorption peak within a region of 30 to 300 GHz. An antenna element includes the circuit substrate described above, a power feeder provided inside the multi-layer substrate of the circuit substrate, and an antenna provided on a surface of the circuit substrate and connected to the power feeder. A method for reducing noise in a circuit substrate including a multi-layer substrate includes, by a millimeter wave absorber provided inside the multi-layer substrate and having an electromagnetic wave absorption peak within a region of 30 to 300 GHz, absorbing unnecessary electromagnetic waves diffused in the multi-layer substrate to reduce noise in the circuit substrate.
