I want to create a signal jammer using arduino but without using a rf module. Since arduino can generate an analog signal, can I transmit that signal using an antenna or do I need something else to transmit that signal?
Forget it. Such devices are illegal in all countries. You would be a subject of interest of the law, the police.
You will not get any support for Your plans on this Forum.
For the time being lets forget about the fact that whether this is illegal or not. I am simply creating a college project and require someone to clarify my doubt.
No! Nothing is forgotten here! Get Yourself another Project!
The same question popped up here a short time ago and it was turned down heavily. Was it You trying this earlier?

If you're thinking of analogWrite() that's actually just a quickly switched digital 0V / 5V signal.

Your Arduino already creates RF signals. Just turn your AM radio on and hold it near the running ARduino. Attach a wire to ANY of the active digital pins and you now have your signal generator. The length of the wire will radiate that wave length more than other wave lengths.
Does this work for you?
