Abstract:
A large periodic array of ideally isotropic antenna elements permits electronic beam scanning and has a performance of power coupling from signal sources at the antenna inputs which is independent of the azimuth (Φ) scanning direction, dependent only on one spatial variable (elevation angle, θ) of scanning Such performance from an antenna array normally can not be achieved using conventional designs. Such an antenna array may be used in communications and radars.
