Abstract :
Antenna architectures based on active aperiodic arrays are considered a promising solution for multibeam transmit antenna embarked on board Earth orbiting satellites. Active aperiodic arrays with equiamplitude excitation represent an alternative to active periodic arrays with tapered amplitude excitation. The paper will offer a preliminary trade-off between the two configurations from a system level perspective.
