摘要
设计了一种椭圆形柱面透镜天线阵列。为改善天线的辐射性能,考虑到高功率应用中的高压击穿问题,提出在横截面为椭圆形组合矩形的天线罩内填充变压器油的方法,并将三元刀型天线阵列密封其内,形成介质透镜天线阵。利用椭圆的几何聚焦能力和介质的缩波效应,提高天线阵列的主瓣增益,并增加天线阵列的电尺寸。通过调整天线阵列的单元间距,相较于不加透镜的阵列结构,该结构的轴向远场电压峰峰值增加41%,远场辐射波束宽度变窄,前后比也得到改善,且增益提高了4.96 dB,功率容量提高338倍,达9.63 GW。
Abstract
A novel ellipse cylindrical dielectric lens antenna array is designed in this paper. In order to improve antenna radiation properties, considering high voltage breakdown based on high power application, this paper proposes filling transformer oil in a nylon radome structure of an elliptical cross-section and rectangular combination, then sealing a knife-shape antenna array in the structure, and eventually forming a dielectric lens antenna array. The geometric focusing capability of ellipse and shrinkage of wavelength helps to enhance the main lobe gain and the electric size of the antenna array. Compared with the traditional antenna array, it shows that the peak-to-peak voltage value along the antenna axis in the far field pattern increases by 41% via changing the array distance, while the far field beam width decreases obviously, and the gain enhancement is 4.96 dB. Furthermore, the front to back ratio gets better, the power capacity is up to 9.63 GW, 338 times greater than that of the former structure.
