Abstract :
A ground receiving phased array antenna system is described for tracking and communication with satellites in low Earth orbit (LEO). Different active array antenna architectures and the minimum number of array elements for meeting the system G/T requirement are evaluated and compared. A general noise temperature model is also developed for evaluating any phased array antenna system. Moreover, this model is also useful for the design and planning of other receiving antenna systems on automobiles, ships, aircraft, satellites,..., etc
