Multiply everything with 24xx/910
Replace xx with a value you consider as being the middle of 2.4Ghz spectrum. maybe it is specified in the original page. Warning: the result will be *big* ! I would go with the simple biquad or GP patch instead. |

But I'd recommend a bicircle - slightly smaller and higher gain - http://www.wikarekare.org/Antenna/bicircle.html |

That 14dBi is most probably a mistake. I bet it's below 10 dBi.
