Sum rules for the antenna input impedance and admittance are introduced. These identities relate the radiation resistance and conductance integrated over all frequencies with the low-frequency capacitance and inductance. They are valid for lossless antennas and particularly useful for small antennas that utilise their first resonance. Numerical results for various antennas are used to illustrate the sum rules.
