摘要

本文提出并验证了一种提高衍射型漏波天线指向性的有效方法，该方法是根据给定的振幅分布使瞄准距离发生变化，从而使分布辐射系统的轮廓发生纵向变化。根据理论计算的规律改变沿孔径方向的瞄准距离，可以改善天线的初始定向特性，降低侧瓣的最大电平，增加天线增益。

Development of a Technique for Increasing the Directivity of an Antenna Array in the Microwave Range

The paper proposes and tests an effective method for improving the directivity of diffraction-type leaky-wave antennas based on the implementation of a longitudinal change in the profile of the distribution-radiating system due to the variation of the aiming distance according to a given amplitude distribution. It has been established that changing the aiming distance along the aperture according to a theoretically calculated regularity makes it possible to improve the initial directional properties of the antenna: to reduce the maximum level of side lobes, and also to increase the antenna gain.
