[0032] A high-gain broadband dielectric lens Vivaldi antenna array operating in the C-band. All structures of the antenna unit are compatible with figure 1 It is exactly the same, using Chebyshev tapered strip line feed, the dielectric constant of the lens in the middle of the slot line is 10.2, the dielectric constant of the dielectric substrate is 2.65, the thickness h=2mm, the antenna unit W=52mm, L=102mm. The antenna array structure is as image 3 As shown, the unit horizontal spacing dx = 35mm, the vertical spacing dy = 17mm.
[0033] Figure 4 The active standing wave curves are simulated for each array element in Example 1. It can be seen that the active standing waves in the working frequency band are all less than 2, which satisfies the index requirements well.
[0034] Figure 5 It is the antenna array gain curve of Example 1, it can be seen that the dielectric lens significantly increases the low-frequency gain of the antenna;
