Abstract
An antenna system comprising (1) a plurality of transceivers capable of being calibrated over the air to improve beamforming and (2) at least one controller communicatively coupled to the plurality of transceivers, wherein the controller (A) identifies a set of partially overlapping subgroups that include the plurality of transceivers, (B) obtains leakage measurements taken in connection with signals emitted by at least one transceiver included in each of the partially overlapping subgroups, (C) identifies, within the leakage measurements, a subset of leakage measurements taken in connection with an overlapping transceiver and multiple non-overlapping transceivers included in the set of partially overlapping subgroups, and (D) calibrates, based at least in part on the subset of leakage measurements, the plurality of transceivers with respect to at least one feature to improve beamforming. Various other apparatuses, systems, and methods are also disclosed.
