Multibeam and multipolarization antenna
2006 First European Conference on Antennas and Propagation, 2006The design of a novel reconfigurable antenna for MIMO systems is presented. Simulation and experimental results shows its capabilities in a multibeam reconfiguration in a 4? steradians environment. It can allow an enhancement in wireless communication employing multipath channel combining with a radiation pattern diversity.

One of the most difficult problems in scanning antenna technology is the realization of wide angle scanning. The proposed architecture seems to overcome the difficulties of realizing complex antennas, and offers high efficiency with wide-angle scanning capabiliy and with (almost) indentical beams regardless of scanning angle.

Multibeam Antenna in Millimeter Waves
32nd European Microwave Conference, 2002, 2002This paper deals with a multibeam antenna in 60 GHz band. This structure is based on a Butler Matrix which fed a four printed antenna array. Two different solutions are presented to avoid the crossing point of the microstrip line : a microstrip-thick slot-microstrip transition or two hybrids 90°.
