Aperture optimization of transmitting antennas for microwave power transmission systems

This paper investigates the aperture optimization method of transmitting antennas for microwave power transmission (MPT) systems to obtain the maximum DC-DC (direct current to direct current) efficiency at a low budget. Two topological models, quasi-rhombus (QR) and quasi-circle (QC) are proposed and compared to the common square (SQ) model. The numerical results show that the QR and QC models can transmit much more power at a little higher beam collection efficiency than SQ one with the same total element number under certain condition.
