5.8 antenna design
Hi
As I don't familiar with the antenna design.
I would like to design an antenna for both 2.4G and 5.8G.
Any suggestion? or Any books or reference that i can read before simulation?
Many Thx.
radiation pattern can be measured by using signal generator and spectrum.
but if you would like to measure the gain then NA would be the fastest and easiest method to go.
use a matched load to connect to one of the port
then use a NA to measure the two port S-parameters. Repeat this steps 2 more times.
You can get 3ports S-parameters.
active networks using op amp
hey thanks
i have tried some of the softwares which are really helpful.
but i would like to ask
"Is it possible to design a active LPF (one stage op-amp only!) with one band got -20db/dec another band got -40db/dec?
rf amp ip3
really ?!
i think oip3 is what qyinn talking about
the 2f1-f2 and 2f2-f1 should be intermodulation of the two tones ,IM3 instead
am i right?!
