The invention belongs to the technical field of
radio frequency energy collection, and particularly discloses a multi-band
radio frequency energy collector which comprises an antenna structure and an EBG metasurface structure. The antenna structure comprises a
metal patch layer, an antenna
dielectric layer and an
isolation layer, and the
isolation layer is connected with the EBG metasurface structure; the
metal patch layer comprises a short-arm fan-shaped
branch knot, a long-arm fan-shaped
branch knot and a double-line micro-strip
feeder line, the length of the short-arm fan-shaped
branch knot is smaller than that of the long-arm fan-shaped branch knot, and the fan-shaped circle center positions of the short-arm fan-shaped branch knot and the long-arm fan-shaped branch knot are connected with the double-line micro-strip
feeder line. By arranging the antenna structure and the EBG metasurface structure,
radio frequency energy can be collected in a plurality of common frequency bands, the array design improves the
gain of the antenna, enhances the
signal receiving capability, expands the effective collection range of the
radio frequency energy collector, and is suitable for an application scene farther from a
radio frequency signal source. The overall structural design is highly integrated, the structure is compact, and the device is suitable for wearable equipment.
