Abstract

A newly synthesis method of planar array antenna for wireless power transmission (WPT) is introduced in this paper. The whole array aperture is divided into several subarrays which can reduce the complexity of the feed network and the cost of the array antenna. Invasive Weed Optimization (IWO) algorithmis used to optimize the subarray division and the excitation amplitude of each subarray. The maximum beam collection efficiency (BCE) and maximum sidelobe level outside the receiving area (CSL) are considered as the evaluation index. The synthesis results show that the proposed method can obtain higher BCE and lower CSL.
