Abstract
Antenna radiation efficiency for electrically small antennas has been discussed in this paper. The radiated field is expressed in terms of spherical harmonic TE and TM modes and radiated and dissipated powers are described by this modal excitation coefficients. By carefully evaluating the above coefficients, upper bound of the radiation efficiency has been estimated.
