Abstract :
This paper presents an implementation of analogue baseband beam steering and its digital counterpart as an attempt to compare between both methods for LEO satellite applications. Both methods are explained, implemented and compared in terms of different aspects such as power consumption, space qualification, flexibility, and speed of steering for a 1×2 prototype.
