Default What's the Impulse response of a loop and dipole antenna?

Since antennas have reactance and radiation resistance, are they always
critically damped, or will they ring-down?

Is this implied by a swr plot? Can I take 3db points as antenna
bandwidth and assume a radiation-resistance loaded-Q from that?

Does feed-point impedance change radiation resistance?

Thanks
