Abstract

The invention discloses a sub-array dividing method of a rectification antenna array. The method comprises steps of inputting rectification antenna array feature parameters, rectification channel efficiency parameters, radiation power parameters and sub-array dividing type parameters, acquiring a radiation power density curve, acquiring a rectification channel efficiency curve, acquiring a sub-array rectification efficiency expression formula, building a target function according to the sub-array rectification efficiency, conducting even sub-array division to the rectification antenna array, selecting an optimized design variable according to the sub-array dividing type, acquiring a constraint function according to the sub-array dividing type, building a rectification antenna array sub-array dividing optimization module, solving a rectification antenna array sub-array dividing optimization module, outputting a sub-array dividing scheme, and acquiring each sub-array module unit number of the sub-array dividing scheme. With rectification efficiency as the target, sub-arrays of the rectification antenna array is divided; and maximum of the whole rectification efficiency of the rectification antenna array can be achieved.

Description

technical field [0001] The invention belongs to the technical field of radar antennas, and in particular relates to a rectifying antenna array sub-array division method in the technical field of radar antennas. Background technique [0002] The space solar power station is a system that collects and converts solar energy into electrical energy in space, and transmits it back to the ground through a wireless energy transmission device, and then converts it into ground power through a ground rectenna. It can provide human beings with abundant and reliable clean energy. The rectenna that converts microwave energy into direct current on the ground is an important part of the microwave wireless energy transmission system. Its receiving and conversion efficiency is related to the success or failure of energy wireless transmission. Therefore, scholars at home and abroad have conducted research on rectenna receiving and converting microwave energy. Research, trying to improve its co...
