Radio wave lens antenna device including Luneberg lens to receive/transmit radio waves from/to geostationary satellite and a pointing map

摘要

A radio wave lens antenna device comprising a hemispherical Luneberg lens (2) made of a dielectric material, a reflecting plate (1) having a larger size than the diameter of the lens (2) at a half-cut surface of the sphere of the lens (2), an antenna element (4) provided at the focal point of the lens (2), a retainer for retaining the antenna element, and a mounting portion (5) for mounting the antenna device on an installation portion, the reflecting plate (1) being mounted on the installation portion so as to be substantially vertical relative to the ground.
