Abstract
A multiple beam array antenna system including a first group of right-handed circularly polarized subarrays and a second group of left-handed circularly polarized subarrays. Combined signals from the right-handed subarrays are output via low noise amplifiers to a first electromagnetic lens while the outputs of the left-handed circularly polarized subarrays are sent via low noise amplifiers to a second steering electromagnetic lens. A satellite selection matrix output block allows a user to tap into signals from right-handed circularly polarized satellites, left-handed circularly polarized satellites, and linearly polarized satellites. A plurality of satellites (e.g. right-handed satellite 'A' and linearly polarized satellite 'B') may be accessed simultaneously thus allowing the user to utilize both signals at the same time.
