Abstract
An antenna for wireless communication includes a spherical reflector and one or more feeds. The spherical reflector includes an inner portion made of material that reflects radiofrequency (RF) beams, and an outer portion positioned on an edge of the inner portion, the outer portion being made of metamaterials that can be controlled to be reflective of or transparent to RF beams. The one or more feeds are configured to form one or more RF beams reflected off the spherical reflector. In some implementations, the antenna includes one or more processors configured to form one or more RF beams using the one or more feeds, and control at least a part of the outer portion of the spherical reflector to reflect an RF beam of the one or more RF beams or be transparent to the RF beam based on the one or more RF beam.
