| Abstract(in English) | In this report, Near-field around a λ/2 dipole antenna, surrounded by a metal frame, was analytically examined, and Far-field radiations were also examined by the method of near-field to far-field transformation, using the analyzed field-data. At first, accuracy of far-field estimation due to near-field sampling, which divides virtual closed surface surrounding an antenna, was examined by only λ/2 dipole antenna, and the convergence of estimation was clarified. Next, Amplitude and phase distributions around a λ/2 dipole antenna surrounded by a metal frame were examined, and far-field radiation characteristics were estimated using the analyzed field-data. As a result, relative differences of estimated values, between with / without metal frames, is within 0.426 dB. Hence the affection on estimation accuracy due to metal frame, surrounding a λ/2 dipole antenna, is a little in this case. |
