Abstract

One approach of solving the synthesis problem of the microstrip antenna array according to the prescribed magnitude pattern is considered. The mutual coupling of the radiators is taken into account in approximation of the given current distribution on the radiators. The synthesis problem of the finite antenna array consists in determining such amplitude-phase distribution of voltages on the entrances of array elements which create the amplitude directivity pattern (DP) arbitrary close to the given one. The Tichonov functional is used as optimization criterion. It characterizes the mean-square component deviation of the given and synthesized amplitudes DP and put the limitations on the norm of the excitation sources of the array. Further, the finding of the solutions, investigations of their quantity and qualitative characteristics are reduced to the numerical solving and research of the Euler equation for the considered functional.

按规定的幅度指向性图合成微带天线阵列

提出了一种按规定幅度图解决微带天线阵综合问题的方法。在近似给定的散热器电流分布时，考虑了散热器的相互耦合。有限天线阵的综合问题在于确定阵元入口电压的幅相分布，使之产生任意接近给定的幅相指向性图。采用Tichonov泛函作为优化准则。它描述了给定和合成振幅DP的均方分量偏差，并对阵列的激励源范数进行了限制。此外，解的寻找，对其数量和定性特征的研究被简化为所考虑的泛函的数值求解和欧拉方程的研究。
