摘要： An apparatus includes a plurality of conductive structures having first sides and second sides opposite the first sides, wherein the second sides of the plurality of conductive structures are configured to be physically coupleable with a printed circuit board (PCB) of a receiver or a transmitter. The first sides of the plurality of conductive structures are configured to be spaced from the PCB by a first distance when the plurality of conductive structures is physically coupled with the PCB. The apparatus includes an antenna having a first side and a second side opposite the first side. The first side of the antenna includes a radiating side of the antenna and the second side of the antenna is disposed closer to the plurality of conductive structures than the first side of the antenna when the plurality of conductive structures is physically coupled with the PCB.

摘要： Systems, methods, and non-transitory media are provided for cross-coupling modeling and compensation. An example method can include determining one or more cross-coupling coefficients representing electrical cross-coupling within a component of a phased array antenna, wherein the component of the phased array antenna includes one or more signal paths between one or more beamformers of the phased array antenna and a set of antenna elements of the phased array antenna; based on the one or more cross-coupling coefficients, modifying one or more beamforming weights calculated for one or more signals routed via the one or more signal paths, wherein the modified one or more beamforming weights compensate for the electrical cross-coupling effect within the component of the phased array antenna; and applying, by the one or more beamformers, the modified one or more beamforming weights to the one or more signals routed via the one or more signal paths.
