Abstract :
This paper presents the formation of an adaptive virtual array antenna in a parabolic reflector illuminated by a tri-mode circular waveguide feed. The modes of interest are the TE11, TE21, and TM01 type modes. By appropriately exciting these modes in the primary feed, the effective source of radiation is displaced within the reflector aperture while the resulting secondary patterns remain axial.
