Flat reflector antenna has metallic parallel dipoles of different lengths and made of dielectric laminate material for performing phase control and orthogonal polarization

摘要

The reflector antenna includes antenna units, each consisting of metallic parallel dipoles of different lengths and made of dielectric laminate material formed on a metallic plane. The antenna units reflect the electromagnetic field from a feeder, and form a shaped beam with the use of a field phase adjusting mechanism. Phase control is performed by adjusting the lengths of the dipoles. Orthogonal polarization can be controlled by using a second layer of dipoles located on the bottom face of the dielectric perpendicular to the upper face.
