Summary:
An extremely large scale periodic array antenna is required for the power transmission in the space solar power systems. Analysis of the array antenna is important to estimate radiation property of the array antenna, but a full-wave analysis requires too much computer memory and too long CPU time. In order to overcome this difficulty, the impedance extension method is proposed as a method of approximate analysis for a huge periodic array antenna. The active impedance and radiation pattern of the array antenna are presented. It is shown that the edge effect of the array antenna is very small in a huge array by error analysis of the active impedance and the radiation field for the impedance extension method.
