Abstract

The plane-wave spectrum concept is used to derive an expression for the radiation pattern of an antenna in a two-dimensional system and an investigation is made of the effect of the aperture size of the measuring antenna on the pattern obtained. It is shown that measured sidelobe levels either above or below the far-field values may be obtained. Measurements of near-field antenna radiation patterns are carried out in a parallel-plate pattern range, and the predicted effects of measuring antennas of finite size on the beamwidth and sidelobe levels of the measured patterns are confirmed experimentally.

用大天线测量近场辐射图的研究

利用平面波频谱的概念推导了二维系统中天线辐射方向图的表达式，并研究了测量天线的孔径大小对得到的方向图的影响。结果表明，测量的旁瓣电平可以高于或低于远场值。在平行板方向图范围内进行了近场天线辐射方向图的测量，并通过实验验证了有限尺寸测量天线对测量方向图的波束宽度和旁瓣电平的预测影响。
