Antenna arrays or systems > Arrays of individually energised antenna units similarly polarised and spaced apart > Antenna units of the array energised non-uniformly in amplitude or phase, e.g. tapered array or binomial array

CPC:

Antenna arrays or systems (arrangements for changing or varying the orientation or the shape of the directional pattern of the waves radiated from an antenna or antenna system H01Q3/00) > Arrays of individually energised antenna units similarly polarised and spaced apart > Antenna units of the array energised non-uniformly in amplitude or phase, e.g. tapered array or binomial array
