I have this RF remote control that I'm trying to understand (here is spec: http://www.telran.co.il/images/980305%20QK-M04%20TECH%20SPECS.pdf ).
I recognize crystal oscillator that is responsible for getting required frequency of the signal, I understand how this hcs301 chip provides KeeLoq encryption, I recognize a battery as a power source ;) . But what here is actually generating the radio signal? I cannot find anything resembling an antenna here, and this remote has quite a long range (about 100m).
Could someone find an antenna here and explain what component(s) is responsible for generating an actual radio signal in this device?
