摘要

背景。完美反射半平面上的对称槽线是有限维理想平面上槽天线的良好数学模型,在实际应用中具有高增益和宽频带。这些天线用于基于微波和光体集成电路的超高速信息处理系统。的目标。本文给出了由具有不同槽扩展规律的对称槽线激发的完全反射半平面辐射问题的解法。方法。采用傅里叶变量分离法求解该问题,得到连接天线辐射场和间隙激励场两分量的格林张量函数。结果。结果表明,在远区,理想反射半平面的辐射场由主偏振和交叉偏振两部分组成。格林张量函数具有复数形式,由两项组成。通过对Green张量函数的分析,揭示了每个项参与远区场的形成,论证了辐射的机理,并得出了槽辐射的已知特殊情况。结论。实验研究证实了该数学模型的有效性。

The structure of the radiation field of a symmetric slot line perpendicular to the edge of an infinite half-plane, taking into account the cross-polarization component
Background. Symmetric slot lines on a perfectly reflecting half-plane are good mathematical models for slot antennas on an ideal plane of finite dimensions, which in practice have a high gain and operate over a wide frequency band. These antennas are used in ultra-fast information processing systems based on microwave and optical volume integrated circuits. Aim. The work presents a solution to the problem of radiation of a perfectly reflecting half-plane, which was excited by a symmetric slot line with a different law of slot expansion. Methods. The problem was solved by the Fourier variable separation method, by which the Green tensor function was obtained, which connects the two components of the antenna radiation field with the excitation field in the gap. Results. It is shown that in the far zone, the radiation field of an ideally reflecting half-plane has two components: the main and crosspolarization. The Green tensor function has a complex form and consists of two terms. The analysis of the Green tensor function shows the participation of each term in the formation of a field in the far zone, demonstrates the mechanism of radiation and leads to known special cases for slot radiators. Conclusion. The validity of the presented mathematical model is confirmed by experimental research.
