Hi David,

= >Hi Clemens, I'm not sure I understand your question.
= The 3 dB bandwidth is f0/Q and  Q is defined as X/R
= where X is the reactance of the inductor and the capacitor at the
resonant frequency.
The lossless-Q of a small a= ntenna is a useful academic quantity, and is
the reactanc= e divided by the radiation-resistance.  It gives the maximum
theoretical Q for any given small antenna, and then the actual Q = can be
measured on the real antenna.  The radiation = efficiency is the lossless Q
divided by the actual Q, by = the equations:
Qlossless =3D X/Rrad,
Qa= ctual =3D X/(Rrad+Rloss),
Qactual/Qlossless =3D Rrad/(Rra= d+Rloss) =3D radiation efficiency.
An interesting limit f= or small antennas is the minimum lossless Q that can
be a= chieved, and was derived by Chu in 1948 from only the frequency and
the size of the antenna.
