More Information
Summary:RF (Radio Frequency) power harvester 1 comprises a dielectric substrate 3 and an antenna on the substrate 3 for coupling with an RF electromagnetic or EM field, wherein the antenna further comprises at least one track of conductive material arranged to provide at least one loop 13 around an annular region at the edge of a first face of the substrate 3. A signal collection gap 17 in the loop 13 provides an electrical connection for obtaining an RF signal from the antenna. Two signal links 9, 11 are coupled to the gap 17 and arranged to carry an electrical signal into a region 27 on the substrate 3 surrounded by the annular region. The at least one track may comprise a first track 13 arranged to provide a first loop, and a second and third track 19, 23 surrounded by the first loop.
