(under subclass 776) Subject matter wherein the wave guide or coupling path of the respective antennas have significant phase characteristics in the transmission of energy therethrough, to modify the relative phase relationship of the transmitted radio wave energy of the respective antennas at their coupling to space, or to modify the relative phase relationship of the received radio wave energy in passing through the antennas and/or coupling paths.
(1) Note. The different phase characteristic is usually secured by a delay network in the coupling path of one of the antennas or a dielectric delaying mass in the wave guide path of one of the antennas.
