Abstract(in English) There is a component that is zero at the port in the current distribution of a dipole antenna. The electric influence of a dipole can be almost eliminated by loading the port with the reactance of j/α, where a is the ratio of the current component to the port voltage. Therefore, even if a dipole is surrounded with some dipoles, the input impedance of the dipole becomes almost Z'_<11> that is the input impedance when the dipole is isolated as long as each surrounding dipoles n are loaded with the reactance of j/α_n. Since a is hardly dependent on the arrangement of the dipoles and Z'_<11> is the characteristic of the isolated dipole, the expression of the relation between the impedance-matrix elements Z_, which hardly depend on the arrangement of the dipoles is obtained. While clarifying this expression, the factor depending on the interval of dipoles is also investigated.
