Theory behind this antenna design

Want to understand the equations on M. Erskine's website? Mathematically inclined?

With reference to the hand drawn template on »osiris.urbanna.net/antenna_desig···emplate/ you can find the gain calculation on page 22 and the k=0.65 on page 25 in this paper:
»www.ece.mcmaster.ca/faculty/geor···_L14.pdf

I'm still searching for the half power beam width equation.

Interesting to note from the pdf of Prof Georgieva's class notes that the first reflector system was made by Hertz in 1888 (cylindrical reflector fed by a dipole). Sounds like the antenna design in this thread.

bbarrera;

Exceptionally nice link! Thank you very much. I downloaded her whole site and am now digging thru the math. The lady is very bright and writes a mean .pdf file.

Thanks for that nugget.
