I am making a GSM + GPS Board, and we don't want to put an external antenna on top of it via any sort of connection.
Primariliy to reduce the cost. I've seen a VTS system with an onboard antenna which gives good enough signal even when the unit is in the basement or indoors.
Now i am not getting any sample reference or guides to work on it. Anyone can point me a guide / pdf / page where these things are xplained ?
We dont want to purchase an antenna we want to have an antenna on our PCB board itself.
