Power Transfer Efficiency Between Circular Antennas with Gaussian Amplitude Distribution in Fresnel Region
摘要
Abstract
The power transfer efficiency between two circular aperture antennas in the Fresnel region is analyzed, and the analytical expression of power transfer efficiency between two focused Gaussian illumination circular antennas is given in this paper. The power transfer efficiency is calculated according to differentσand C. The results show that the optimum il-luminations that maximize the power transfer efficiency can be approximated by Gaussian illuminations. There is a most suit-able illumination constant σ for each C that maximizes the efficiency. When the Fresnel number is small, the optimumσis approximately equal to C/3, and then it approaches to C/2 as C increases.关键词
