With an antenna, the only place for energy to go is to either be radiated or converted to heat. A good antenna will do all of the former and none of the latter. For a capacitor, it is designed to store energy but almost all of the time the real goal is for that energy to be released back into the circuit in the right way. So any energy lost to heat is a waste, and this parameter is known as the "parasitic resistance", and lower is better. | |

Just that it (the energy) does not go very far and is converted to heat on the spot? | |
