Summary:
The impedance extension method (IEM) has been proposed so far, as a method for analysis of a huge-scale periodic array antenna for power transmission from space solar power systems (SSPS) to the earth[1][2]. Since the IEM is an approximate method based on active impedance properties of elements in the periodic array antenna[3], the IEM can only be applied to the periodic array antenna. However, periodicity of the array antenna can not be kept in the areas where antenna elements are broken due to the trouble in feeding circuits or feeding cables. In this paper, it is reported that the IEM is extended to be valid to a two-dimensional large-scale periodic array antenna with faulty elements.
