I have multiplied the ABCD matrix for even and odd mode but it doesn't show the same results

Check the multiplication.. It should be same.

small correction, your abcd for a OC shunt stub is C = j/root(2) and -j/root(2). because in this instance, characteristic impedance is sqrt(2) for the stubs. thank you for the video

it comes out to the same end matrix you got, just clearing it up for people like me who could not see it immediately :D

Why lemda bai 2 is 180

When you convert physical length to electrical length you multiply it by (2*pi/lambda). So (lambda/2)*(2*pi/lambda)= pi radian=180 degree

@@RFDesignbasics is there any conversion formula for physical and electrical length

I have written it above.. it's also same for converting the path difference into phase difference. Either way you can understand.
