Oh, ok. I want to increase the strength of a wifi signal.

You will probably find a lot of help if you "nose" around your local
college (computer/physics/engineering instructors can point you to the
best minds.) The youngsters are all into stretching wifi distances to
the max.

Here is a page to get you started:

After experimenting with many different antennas at the feed point, I
kept the biquad in the original plans. Your dish is larger than the one
I use (mine is identical to the one on the page--my feed is slightly
modified ...)
