摘要
A mission-flexibility antenna includes a reflector and at least a first source and a second source of radiofrequency signals, which sources are arranged in front of the reflector, the reflector having a focal point and each source having a phase center, and wherein the sources are independent, fixed and connected to separate radiofrequency feed systems defining different and predefined polarization and/or operating frequency characteristics, and in that it additionally includes means of displacement and orientation of the reflector from a first position in which the focal point of the reflector is placed at the phase center of the first source to a second position in which the focal point of the reflector is placed at the phase center of the second source.
