On the design of clustered planar phased arrays for wireless power transmission

[摘要] References(14)Cited-By(1)In the framework of wireless power transmission applications, the design of planar phased arrays providing maximum beam collection efficiency (i.e., maximizing the ratio between the power radiated over a target area and the total power transmitted by the array) through a sub-arrayed architecture is addressed. The degrees-of-freedom of the synthesis problem at hand (i.e., the membership of the array elements to clusters and the sub-array amplitudes) are determined by means of an excitation matching technique exploiting the knowledge of the set of independent and optimal weights providing maximum transfer efficiency. A set of representative results is reported to assess the reliability and effectiveness of the approach in yielding beam efficiency values close to the optimal ones with a limited number of sub-arrays.
