摘要：
Polarizability has been shown to be a useful route for the calculation of the directivity-to-quality-factor ratio (D/Q) bound of electrically small antennas of arbitrary shape. We demonstrate that the same integral-equation-based moment method formulation used to determine the radiation patterns and input impedance of such antennas can also be used to estimate its polarizability, and hence D/Q bounds.
