Abstract
A method and antenna system for achieving remote electrical tilt by a hybrid use of analog and digital phase shifting are disclosed. According to one aspect, a hybrid remote electrical tilt (HRET) antenna system includes a digital beamformer configured to apply a first set of at least one phase shift to each antenna subarray of at least one group of at least one antenna subarray. The at least one phase shift is determined to suppress sidelobes when a beam is steered to an elevation by the digital beamformer. The HRET antenna system also includes at least one analog phase shifter configured to apply a second set of at least one phase shift to at least one antenna subarray of each group of at least one antenna subarray so that a combined phase shift applied to each antenna element steers the beam to the elevation while suppressing the sidelobes.
