The only conundrum is you are trying to make a weapon to hurt people. Not worried though since it’s clear you have no grasp of what you are asking. You have a lot of learning to do about basic electronics.
@leumas95 said the other thing I was going to say… “5G” cellular is different than “5GHz” wifi. Neither one operates anywhere near the resonant frequency of implants nor do they put out enough power to do the damage you want it to.
