A novel high-efficiency rectenna for 35GHz wireless power transmission

Rectenna is one of the keys to microwave power transmission; microstrip patch antenna is very suitable to such places as microwave plane and high platform. Aiming at the low efficiency of ordinary theory and method, a new theory was introduced and a 35GHz square patch rectenna was designed, it decreased the difficulty of design and increased the efficiency of system. The results of simulations reveal that the conversion efficiency of system reached to 52% and proves its feasibility and higher efficiency.
