Each of the main mission antennas on an Iridium satellite consists of more than 100 of these small antennas, manufactured by Raytheon. They receive signals from ground-based phones, and the signals are then processed by onboard computers. After processing, the original signal is either retransmitted to the ground or passed to another satellite.
