Amplifier for active microstrip antena

Amplifier for active microstrip antena

Amplifier for active microstrip antena

(OP)
Hi,

I would like to transform a passive 2.45 Ghz patch antena into an active one. Does someone has some schematics, layout or advice to give me to build a low noise amplifier?
 
The antena is made for short range wireless (10-15 meters).

Thanks,
Thomas K.

I would keep the same antenna, add a MMIC amplifier followed by a stripline bandpass filter, since they are lower loss than LC BPF.

Hope this helps.

Victor
