Theoretical investigations on the centre-fed full-wave dipole antenna with feed-points displaced along the axis of the dipole

An analysis of a centre-fed full-wave dipole antenna with feed-points displaced along the dipole axis is presented. Mathematical expressions for the far-zone radiation field, radiation resistance, power gain and effective length of the antenna are developed. The variation in the properties of the full-wave dipole for various values of feed-points displacement along the dipole axis are discussed.
