These beams can be obtained by means of reflector antenna with two or three feeds, or by using linear (2D tracking) or planar (3D tracking) arrays. The latter solution is usually preferred since antenna arrays are easier to build and the beam patterns can be steered electronically. Moreover, such a structure can be installed on mobile vehicles. date: 2011-01 date_type: published institution: University of Trento department: informaticat refereed: FALSE referencetext: [1] M. I.
