The properties of an inclined form of a planar log-periodic antenna are described. The planar antenna has radiation characteristics similar to those of a halfwavelength dipole, but with a bandwidth as large as desired. It is shown that, when the planar antenna is inclined about one axis of symmetry, the resulting structure has unidirectional radiation patterns.
