Abstract:
A phased-array antenna, comprising:a plurality of transmit/receive radiator elements arranged linearly in rows and in columns; and,a power distribution and phase shifter network for generating predetermined transmit/receive characteristics of the signals that are emitted and/or received by the transmit/receive radiator elements; and, wherein the power distribution network includes, for achieving a transmit/receive changeover for a selective connection of the power distribution and phase shifter network to a transmitting and/or receiving arrangement, a serial feed line comprised of a waveguide having a first port at one end for coupling the waveguide to a transmitting arrangement and a second port at its other end for coupling the waveguide to a receiving arrangement, a predetermined number of coupling in/coupling out locations formed in the waveguide along its longitudinal direction to couple in/couple out the wave which can be guided in the waveguide, and a respective connecting waveguide coupled to each of the coupling in/coupling out locations to connect the waveguide with respective phase shifters of the phase shifter network.
