| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In the radiative near field, electric fields mutually cancel each other on a receiving plane because of the phase difference between the center and the edge of a transmitting plane. In this paper, we investigated whether high efficiency can be realized by setting the electric fields to 0 of transmitting plane corners. As the result, the beam collection efficiency was improved in the theoretical calculation and in the case of an array antenna. Further, we calculated the phase difference between the center and the corner of a transmitting plane in the distance where the high efficiency was realized. We found the efficiency is improved in the distance where the phase difference is larger than 1.3 rad if the corner size is about 4 % or less of a transmitting plane. | |
