DESCRIPTION:Recent developments in both terrestrial and non-terrestrial net
 works are focused on multiple beam and reconfigurable antenna systems as a
  mean to increase data rates and to provide more flexibility in resource a
 llocation. Some synergies between space and terrestrial systems are emergi
 ng as the fifth generation (5G) of wireless systems introduce millimeter-w
 ave frequencies for short range and indoor applications. This provides a u
 nique opportunity for transfer of technology\, as requirements for satcom 
 user terminals and cell tower antennas present some similarities. While ph
 ased array antennas are getting a great deal of attention\, their cost sti
 ll remains high for mass market applications and alternative solutions bas
 ed on simpler beamforming techniques are being considered. This talk will 
 review well-known quasi-optical beamforming techniques and discuss their r
 espective advantages and limitations. Recent developments\, including prac
 tical demonstrations of novel lens concepts and the first in-orbit demonst
 ration of reflectarray technology by a commercial equipment provider will 
 also be presented. These antenna solutions\, originally developed for spac
 e applications\, may also find use cases in terrestrial networks.\n\nSpeak

 Some synergies between space and terrestrial systems are emerging as the&n

 requencies for short range and&nbsp\;indoor applications. This provides a 
 unique opportunity for transfer of technology\, as requirements&nbsp\;for

 hile phased array&nbsp\;antennas are getting a great deal of attention\, t
 heir cost still remains high for mass market&nbsp\;applications and altern
 ative solutions based on simpler beamforming techniques are being&nbsp\;co
 nsidered. This talk will review well-known quasi-optical beamforming techn
 iques and discuss&nbsp\;their respective advantages and limitations. Recen
