double ridged antenna

Hello,

Does anybody know how to calculate the aperture for this kind of antenna?
Also is there a tutorial that helps to calculate the equation or the slope for ridges?

Thank you in advance,

Best regards,

to simplify you work
Look for tutorial or equation that calculate the slope of vivaldy antenna
and for the horn look at it like regular horn.

PL

the aperature maybe is the same as the square horn

The ridges are function of exponential.
They purpose is to match waveguide impedance (usually H - shaped) to free space impedance Zo.
I'll find some paper suitable for you because my friend designed such type of antenna working in the band 200 MHz - 2.2 GHz
