.~.~.~ With control of individual antenna (e.g., lobe switching or steering)
DEFINITION
Classification: 343/777
(under subclass 776) Subject matter wherein at least one antenna has in its wave guide path or its coupling to the transmitter or receiver, structure such as a switch or adjustable impedance, which alters the amplitude or phase of the energy passing through the path or coupling to modify the radiation or polarization pattern of the antenna.
(1) Note. Included here are plural wave guide antennas having switches in the coupling paths for lobbing the antenna
beam, or having variable impedance in the coupling paths for steering the composite beam from the antennas.
