摘要

在MathCad环境中，模拟了由不同辐射体组成的线性和平面均匀天线阵列在较大范围内距离和辐射体数量变化时的方向性。考虑了线性、矩形和方形孔径的天线阵列。确定了给定散热器数量下天线阵列的最高可达指向性。结果表明，当信号波长小于辐射体之间的距离时，天线阵列的发射和接收信号的形状和光谱会发生畸变。

Directivity of large antenna arrays

Directivities of linear and plane homogeneous antenna arrays consisting of different radiators were simulated in the MathCad environment when distance between the radiators and numbers of radiators were varied in the wide limits. Antenna arrays with linear, rectangular and square aperture were considered. The highest attainable directivity of the antenna array with given numbers of radiators was determined. It was shown that the antenna arrays distort shapes and spectra of transmitted and received signals when the signal wavelengths are shorter than the distance between the radiators.
