Summary:This letter presents the compact and high-efficiency Class-F rectifier with a novel multiharmonic termination network for wireless power transfer (WPT). This network deploys only four transmission lines (TLINs), which allows harmonic control up to the sixth order and provide fundamental input impedance matching, simultaneously; enabling an efficient Class-F behavior. The implemented rectifier exhibits a superior power conversion efficiency of 82.2% at 2.4 GHz for an input power level of 15 dBm, and has a size of <inline-formula> <tex-math notation="LaTeX">0.24\,\,\lambda \times 0.16\,\,\lambda </tex-math></inline-formula>, indicating clear advantages in high power conversion efficiency (PCE) and compactness over the other designs.
