Description
Toyon proposes to design a UHF SATCOM antenna for the SEAL Delivery Vehicle (SDV) with the ability to switch between low-angle and high-angle gain patterns. As the mast tilts in rough seas, the antenna can be operated in a dynamic mode that selects either the low-angle or high-angle gain pattern to maintain optimal gain toward a UFO/MUOS satellite. This mitigates the gain rolloff that occurs with fixed-pattern mast antennas in real-world operational scenarios. Reflections off the sea that lead to scalloping of the gain pattern over the low elevation angles will be reduced by raising the antennas phase center to the top of the antenna when selecting the low-angle gain pattern and to the bottom of the antenna when selecting the high-angle gain pattern.
