I would say it depends on the frequency of your LCR meter and the antenna.
If the frequency are the same, it should work.
But you cannot measure with a LCR meter the impedance of a high frequency antenna.
thank you volker_muehlhaus but another queastion, measure the antenna, the parameter of LCR, how big measure voltage I have to set?
and the impedence of the antenna can I measure the capacitor, inductor, resistor with individual, then plus them together?
Raidation resistance models an "imaginary loss", and does not contribute to thermal noise. radiation resistance is in series with metal ohmic losses, ground losses, etc to form the total input resistance.
