waveguide slot antenna

i'm designing a waveguide slot antenna array with a uniform feeding, but i don't know how to caculate the slot shift,length,space. anyone has some example program? thanks.

i have no experience about it. i think you should refer to some example in ieee. Good luck !

Hi
I have here calc. examp. of 10GHz slotedline
+list of books
g=admittance/16element

thanks!
and do you know how to caculate the resonate length of a waveguide filled with dielectric?
i find some data from elliott's paper, but it seems the voltage of slot should be measured first of all.

u can refer to Antenna Handbook by Lee and Lee u will get help frm there

slot length is around 0.48*wave guide wavelength
slot offset is decided by the normalized admittance of the slot, which is 1/n for uniform distribution, n is the number of slot.

if mutual coupling is very strong (dielectric-filled or height-reduced waveguide), you can use Elliot's iteration method.
