  • Abstract
    It is required to change a collimated beam in a normal state to another pattern in order to cope with system emergencies. This paper proposes an instantaneous expansion of the beam for a phased array antenna. The design principle of the antenna is described on the basis of the phase distribution of a spherical wave. The simulation results are presented.
