Abstract

In some embodiments, the multiple antennas are cooperated in the system to provide simultaneous communication with multiple remote sites. Embodiments comprises a first variable inclined continuous transverse stub (VICTS) antenna that comprises a perimeter and an inactive region within the perimeter, a second VICTS antenna positioned at the inactive region of the first antenna, a first antenna control that steers the first antenna, and a second antenna control that steers the second antenna independent of the first antenna. In some embodiment, an antenna system is provided that comprises a first turntable having a perimeter, a first antenna having a perimeter, where the first antenna is secured on a first surface of the first turntable, a second antenna positioned proximate the first antenna and extending within the perimeter of the first turntable, where the second antenna is steerable independent of the first antenna.
