may i know what are you testing? because for bluetooth, the minimum good level is -70dB at a place where no other bluetooth unit is working. it means that if i test a unit in a area that is there are more unit working and at -70dB the unit is still passing that means my unit tested is good. it...
if you want long distance communication for 403.5Mhz then use helical antenna for simulation, but for short distance fr4 will work but you have to tune it with rlc circuit. i hope this helps...
if you can explain why are you doing this and what is the specific application you want to apply to this project?
its because microcontroller is programmable and so is the bluetooth also. if you have bluetooth module you can program it directly to pair with your phone and do as you like..
in our company, after the antenna design is finish in CST, we counter check the antenna using our network analyzer. in most cases our CST result for S11 is much better compare to the real measured data by the analyzer. in cases of the transmission pattern we go out and test outside to see where...
Re: good Rx Level?????
-70dB is already good. just like for bluetooth application -70dB Rx level is the reference. going to -90dB and still your circuit can recieve well that means you've got a very nice Rx reciever
