How 2 build Grid Antenna Feed?

Can any one help me to find information on building an Feed for
Parabolic Grid Antenna for 2.4GHz of 20dbm signal strength atleast.

I searched on google for hours but i got none designs for Feed for
Parabolic Grid Antenna, i still wonder y? Though there are many for
Parabolic Solid Antenna such as quad type, cantenna etc.

The feed is the same whether it's a solid dish or mesh (grid) dish.

I know the feed is same. What i'm asking is if you see any
semi-parabolic gird antenna there is one long flat plastic feed in
center of the antenna, usually in shape of egg. I want to know the
measurements and design its inside.

I have some of the grid antennas that Hyperlink used to sell where the feed
is enclosed in white plastic that's rounded on the top and outer edge and
flat on the bottom. If this is the 'egg' you mean, inside is what I would
call a 2 element yagi (just a driven half wave dipole and a reflector
element.)
