Abstract (en)
[origin: EP1551078A1] The antenna has an omnidirectional antenna (11) transmitting and receiving electromagnetic radiation beam and having two conical surfaces around z axis. Discrete reflecting units (20) are associated to the antenna (11) and have variable reflectivity based on frequency of the beam. The units are disposed along concentric circles (31-34) centered on the axis, and have bars connected by diodes controlled by continuous voltage.
