Abstract :
Microwave Power Transmission (MPT) can be applied to a greater number of applications provided that higher frequency MPT systems are developed. In particular, we need high efficiency rectennas at higher frequencies. We developed a monolithic microwave integrated circuit (MMIC) rectenna with a resonant frequency of 24 GHz, with dimensions of 1 mm × 3 mm, and whose maximum RF-DC conversion efficiency is 47.9% for a 210 mW microwave input power at 24 GHz with a 120 Ω load. We intend to apply this rectenna to realize simultaneous power and information transmission.
