Abstract(summary):

An improved method used to design high transmission efficiency microwave power transmission (MPT) antenna array is proposed in this article. In this method, the constraint of the transmitting element arrangement is removed by defining the power transmission efficiency different from previous works, and the coupling between transmitting elements is included completely. Two 4 x 4 antenna arrays working at 5.8 GHz are designed and fabricated to verify it. These two arrays are used in two MPT systems, in each system the transmitting array and receiving array have the same geometry. The measured transmission efficiencies of antenna array 1 and array 2 are 65% and 58% when the transmission distances are 10 cm and 20 cm, respectively.
