Abstract
The azimuthal symmetry of the polar diagram of a simple dipole radiator above a ground plane may be improved by bending the ends of the dipole towards the ground plane. Combined with capacitative loading of the dipole and a modified balun, this produces a compact, efficient feed with improved selectivity.
