Hi,
I recently made a project which had a wireless link on it, but i didn't really understand why i did some of the things i did. Basically, i want to why when you use a PCB for an RF circuit that the other side of the PCB needs to be a ground plane? Also, does it matter if the ground plane is broken by tracks connecting components. On my PCB it was and it had a very limited range. Although, the limited range was probably because of the low supply voltage i used. Any information would be really apprciated.
the carrier frequency for the signal was 433 MHz.
