Proceedings PaperBeam Forming Networks For Millimeter Wave Satellite Communications
|Format||Member Price||Non-Member Price|
Several communications satellites now being developed for future commercial and military systems will have the ability to provide electronically controllable antenna patterns for maximum capability and flexibility. The multiple beam antennas which provide this coverage contain one key element known as a beam forming network (BFN). Critical components employing ferrite device technology have recently been developed for use in wide variety of beam forming networks in the millimeter wave region. These components have the required insertion loss, switching energy, size, weight and reliability necessary in satellite applications.
