Abstract :
Future communication satellites will require multiple reconfigurable antenna beams to achieve competitiveness and adaptability in the international marketplace. A preferred method for achieving this is by multibeam active arrays, using separate control MMICs for each beam and common power amplifiers, on transmit. To study the feasibility of this approach, we have designed and built a 37-element dual-beam active transmit array operating at 20 GHz.
