H01Q19/08 - for modifying the radiation pattern of a radiating horn in which it is located
G01S1/38 - using comparison of (1) the phase of the envelope of the change of frequency, due to Doppler effect, of the signal transmitted by an aerial moving, or appearing to move, in a cyclic path with (2) the phase of a reference signal, the frequency of this reference signal being synchronised with that of the cyclic movement, or apparent cyclic movement, of the aerial
G01S1/40 - the apparent movement of the aerial being produced by cyclic sequential energisation of fixed aerials
H01Q3/26 - varying the relative phase or relative amplitude of energisation between two or more active radiating elements varying the distribution of energy across a radiating aperture
H01Q3/2658 - Phased-array fed focussing structure
H01Q13/02 - Waveguide horns
H01Q25/007 - using two or more primary active elements in the focal region of a focusing device
US Classifications
342 - Communications: directive radio wave systems and devices
343 - Communications: radio wave antennas
