An inflatable structure usable as a satellite terminal. An inflatable structure may include an inflatable membrane for forming the structure and two integral RF reflective portions. When the membrane is inflated, the two RF reflective portions oppose each other to form an antenna. One RF reflective portion may be a main reflector and the other RF reflective portion may be a subreflector, both reflectors curvatures that face each other to form a Gregorian antenna or a Cassegrain antenna. In another embodiment, an inflatable antenna may include an inflatable dish including a RF reflective main reflector and an opposing RF transparent dish wall. An inflatable RF transparent support member and an RF reflective subreflector extend from the dish wall. Again, when the antenna is inflated, the main reflector and the subreflector oppose each other to reflect RF energy toward each other to form an antenna. |
