Embodiment 1
[0028] The central operating frequency of the ridge waveguide power divider used in the ridge waveguide slot antenna array in this embodiment is 35Ghz, and the in-band operating frequency is 34.5Ghz˜35.5Ghz.
[0029] see figure 1 , the ridge waveguide power divider used for the ridge waveguide slot antenna array is a single ridge waveguide power divider, which has a feed port 3, a first sub-port 4 and a second sub-port 5, wherein the feed port 3 is located on one side, so The first branch port 4 and the second branch port 5 are located side by side on the other side.
[0030] see figure 2 , the inner end of the ridge of the feed port 3, the inner end of the ridge of the first sub-port 4 and the inner end of the ridge of the second sub-port 5 are connected by a T-shaped block 2.3, wherein the top two ends of the T-shaped block 2.3 Connect the inner end of the ridge of the first sub-port 4 and the inner end of the ridge of the second sub-port 5 respectively, the bottom end of...
Embodiment 2
[0037] In this embodiment, the central working frequency is 17.6Ghz, and the in-band working frequency is 17.3Ghz~17.8Ghz.
[0038] The structure of this embodiment is the same as that of Embodiment 1, see the main structure diagram Figure 1~Figure 5 , Ridge waveguide cross-sectional length Ra = 6mm, cross-sectional height Rb = 4mm, ridge width Rw = 2.8mm, ridge height Rh = 2.6mm. The metal wall thickness of the middle transformation section of the T-shaped block 2.3 is Tb=1.4mm, the transformation section 2.2 close to the first branch port 4 is lower than the height of the ridge Th=1.1mm, and the distance from the edge of the single ridge to the feeder port 3 is Te=1.4m. The lengths of the transformation sections Tf and Tg on both sides of the T-shaped block 2.3 are 4.2mm and 4.4mm respectively, and the length of the transformation section on one side is Tk=4mm. Ta and Td are 4.5mm and 0.3mm respectively, metal diaphragm 2.1 distance Tc=2.225mm from the metal wall of the se...
