摘要

在天线通论的实践课程中,学生很难直接综合天线。提出了一种近似求解综合问题的方法,该方法利用归一化期望天线方向图(AP)与孔径内场的幅相分布未知的归一化天线方向图(APD)之间的二次度量来表示泛函空间中距离的最小化。在这种情况下,AP不一定要与可实现的类相关,并且该领域的APD虽然功能最小化,但可以从适合实现的函数集中选择。最后,以具有精确已知APD的线性天线为例,对该方法的有效性进行了验证。提出了开展实践课的建议。

Methods of studying the antennas synthesis problem in practical lessons
It is difficult to synthesize the antenna directly in practical lessons in general theory of antennas with students. The approximate method is proposed for solving the synthesis problem based on the minimization of the functional representing the distance in the functional space with a quadratic metric between the normalized desired antenna pattern (AP) and some normalized AP with unknown amplitude and phase distribution (APD) of the field in the aperture. In this case the AP does not necessarily have to relate to the class of realizable ones, and APD of the field, while functional is minimized, can be selected from the set of the functions suitable for implementation. Validity of the method is tested on the example of synthesis of a linear antenna with the APs for which the APD is accurately known. The recommendations for conducting practical lessons are given.
