Array antenna architectures for solar power satellites and wireless power transmission

An analytical technique for the synthesis of planar arrays for wireless power transmission is proposed whose aim is to maximize the ratio between the power collected at the receiver to the total transmitted power. The array weights are optimized through an analytical methodology which formulates the synthesis process as a generalized eigenvalue problem. The methodology can be applied for arbitrary geometries of the transmitter array and whatever the rectenna shape. A preliminary numerical validation is presented to assess the flexibility and potentialities of the method.
