Default How to make an excellent wifi (802.11 b/g/n) antenna?

My background isn't on antenna making, in fact, my training is in
Chemical engineering, not physics.

But lately I've spent a lot of times consuming materials I dig from
the Net about antennas, in the effect to learn how to make an
excellent (effective?) wifi antenna.

Specifically, my interest is in the "broadcast" type of antenna ...
trying to find a way to "extend" the range of a typical wifi
basestation using antennas alone (maybe with the help of MIMO
antennas), without "range repeaters" or whatnots.

My brain is now fully clogged, and I'm having difficulties digesting
all the stuffs that I've gotten.

So I desperately need you help.

Is there a place (a forum, a website, a tutorial, and whatnots) where
one can learn about antennas, without having one's brain clogged up,
like mine right now?

What's your suggestion / opinion on how to construct an excellent
(pair) of MIMO antenna for wifi (802.11 b/g/n) ?

Thank you all !


Often gain type antennas already came with the unit. The problem is in
putting the antenna where it will do some good. The other problem is in
losing signal getting it from the AP to the antenna. You can easily lose
any gain from a good antenna in the cable and connectors. On the other hand
it is worth that just to be able to put the antenna where it will do some
good. If it is any consolation, Cat5/6 is cheaper and faster than the AP
itself. Still it is a pain to have to climb and do acrobatics just to push
a reset button. There are excellent base station type antennas, hardware
and feedline that can certainly optimize a signal for blocks away, but they
are expensive and must be properly planned and executed to avoid wasting it
all.

This isn't amateur radio so it really isn't on topic. It sounds to me like
a business opportunity.
