Hi Linco,

well that antenna you provide a link to has an impedance by it's nature of 25 ohms, this means that the simplest way to match it to 50 ohms is to use a pair of them, phased up. Using a 3/4 wave transformer will take 25 ohms and give you 100 ohms, 2 100 ohms in parallel will give you 50 ohms, and your feed point.

as for the antenna modelling software - that's a secret!

cheers,

mr_wlan.
