| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | The mutual impedance and the mutual radiation resistance of the array antenna are expressed, using the fields expansion in terms of vector spherical harmonics and compared. It is shown that, if the elements fields are rotationally symmetry and expansion coefficients are real, the mutual radiation resistance is the real part of the mutual impedance. Next, the first-order approximation of the array gain which includes the mutual impedance matrix explicitly is derived, under the assumption that, the current shapes are not affected by the mutual coupling. Also, the first-order approximation of the array directivity which explicitly includes the mutual radiation resistance matrix is derived. Both expressions have similarities. However, the major difference is that the directivity includes Kronecker product of the conjugate of the input current and the input current but the gain dose not. |
