Ka-band Satellite Phased Array Antenna

ABSTRACT: This proposal addresses an important need of DoD and MILSATCOM for satellite based receivers operating at Ka-Band having multiple beams (as many as 30) capability. Many of these beams need to be independently steered. This has traditionally been a major challenge because, as will be shown, the architectures that are required are very component intensive, which has made such antenna systems very costly and power consuming. Based on new and recent technological advances that have been made in Silicon Germanium, we have evolved a new and innovative concept that truly advances the state of the art for phased arrays, not only for this program but for other programs also. BENEFIT: Prior to this effort, phased arrays were large, high cost, high power, and had limited success on space platforms. With this innnovative development, not only will the DoD have the ability to successfully place these arrays on space platforms at a reasonable cost. Commercial satellites will also greatly benefit from this development.
