dual rigid horn antenna

Dears,

In the past I have successfully designed the UWB patch antenna. I feel great thrill and enjoyment in designing antenna Nowadays, i am working on Dual rigid horn antenna. i have studied some basic concepts of horn antenna but i am facing difficulty of the design procedure. i.e. i dont know the formula and the equations. though i knew which parameters to calculate but the formulas required foir those parameters are not known to me.i have searched a lot on the internet but find no success.

So, if somebody can refer me to some interrnet links or research papers or e-books discussing about the design formulas i shall be thankfull to HIM/HER

Did you have a chance to refer to the book called antennas from theory to practise and other books.
