How to calculate the frequency of an antenna with guided wavelength and slot length?

hi all,

i have attached one ieee paper. in that they explained the opration of the antenna wit the guided wavelength and slot length. how to calculate? i want to get mathematical calculations to get the frequency of operation.

Hi,

the structure looks rather simple but the problem is that even for this simple structure an closed analytical solution of Maxwell's equations are hard or even impossible to find. There is no simple formula to calculate the slot length. You can do some estimations but for a accurate calculation you have to use numerical methods (FDTD, FIT, FEM, MoM).
