Antenna element with high gain toward the horizon

摘要

An air-to-ground network communication device may include a conductive groundplane and an antenna element. The conductive groundplane may be disposed to be substantially parallel to a surface of the earth. The antenna element may extend substantially perpendicularly away from the groundplane and may have an effective length between about 1λ, to about 1.5λ. The antenna element may be disposed at a distance of about 0.5λ to about 1π from the groundplane.
