Embodiment approach 1
[0027] A V-shaped microstrip meander slow-wave structure, such as image 3 As shown, it includes a microstrip transmission line structure formed by a metal base plate 3 , a dielectric layer 2 and a planar metal line 1 . The dielectric layer 2 is located between the metal bottom plate 3 and the plane metal wire 1 , and its shape is the same as that of the metal bottom plate 3 . The planar metal wire 1 is composed of a plurality of planar metal wire segments of the same shape and size connected end to end to form a zigzag structure; wherein two adjacent planar metal wire segments form a "V" shape or an inverted "V" shape, and a "V" shape or an inverted "V" "The included angle (2θ) of the font is less than 180 degrees.
Embodiment approach 2
[0029] A V-shaped microstrip meander slow-wave structure, such as Figure 4 As shown, it includes a microstrip transmission line structure formed by a metal base plate 3 , a dielectric layer 2 and a planar metal line 1 . The dielectric layer 2 is located between the metal base plate 3 and the planar metal line 1 , and its shape is the same as that of the planar metal line 1 . The planar metal wire 1 is composed of a plurality of planar metal wire segments of the same shape and size connected end to end to form a zigzag structure; wherein two adjacent planar metal wire segments form a "V" shape or an inverted "V" shape, and a "V" shape or an inverted "V" "The included angle (2θ) of the font is less than 180 degrees.
[0030] After confirming that two adjacent sections of planar metal line segments form a "V" shape or an inverted "V" shape with equal angles (periodic structure), determine the relevant dimensions (unit: mm) of the above two implementations: a=0.72, b =0.36, p=0...
