suppose there is no delay time (ideal line only)
What do you mean by
no delay time (ideal line only) ?

30/360 * lamda = 1/12* 3e8/60e9 = 420um?
Right.
beta=2*pi/lamda, theta_rad=30/180*pi,
Length=theta_rad/beta=30/180*pi*lamda/(2*pi)=30/360*lamda

is that correct?
Correct.
However "dielectric constant" is considered as wavelength or wave velocity equivalently.

does that mean it is set to be a quarter wave TL?
Yes.
Read message of "spectre -h tline" surely, before posting questions.
