Abstract
Systems and methods are disclosed for an underground antenna structure for radiating through a dissipative medium, the antenna structure. The antenna structure includes a dielectric substrate, a feeding structure disposed on the substrate, and one or more electrical conductors. The one or more electrical conductors are disposed on the substrate, oriented, and buried within the dissipative medium. The electrical conductors are also adapted to radiate signals at a frequency in a half-space adjacent to the dissipative medium. The adaptation include a beamwidth state for one or more of the electrical conductors based at least in part on the relative permittivity of the dissipative medium.
