| Abstract(in English) | The cavity-backed slot antenna is used as an element for the spacetenna of the solar power satellite SPS2000. The spacetenna is a huge phased array antenna somposed of 2.5 million antenna elements. Therefore, it should be noted that the mutual coupling between elements affects the beam scanning seriously. The paper discusses the evaluation method of mutual coupling using the finite-difference time-domain(FDTD)technique collaborating with the second-order absorbing boundary condition(ABC)or the PML ABC. It is found from computations on E-plane two-and four-element array antennas that the FDTD method with the PML ABC gives more accurate estimation of the mutual coupling for the smaller size of the problem space than with second-order ABC. |
