Co-simulation of a complete rectenna with a circular slot loop antenna in CPW technology

This study starts with the design of a planar and compact CPW antenna fabricated on Arlon AD1000 substrate, er=10.35. The antenna is a coplanar waveguide (CPW) fed circular slot loop antenna matched to the standard impedance 50 Ω by two stubs. The goal is to implement this antenna with a CPW RF/DC rectifier to build an optimized low power level rectenna. The rectenna design is restricted to allow easy and fast fabrication of an array with a high reproducibility. The full rectenna is simulated and achieves 10% effciency at-20 dBm.
