    Abstract: An antenna and a base station including the antenna. The antenna includes a sub-array that includes first and second unit cells and a feed network. The first and second unit cells comprise first and second patches, respectively, having quadrilateral shapes. The feed network comprises a first transmission line terminating below first corners of the first and second patches, respectively; a second transmission line terminating below third corners of the first and second patches, respectively; a third transmission line terminating below a second corner of the first patch and a fourth corner of the second patch; and a fourth transmission line terminating below a fourth corner of the first patch and a second corner of the second patch. The first corners are opposite the third corners on the respective first and second patches and the second corners are opposite the fourth corners on the respective first and second patches.

    Abstract: Reciprocity base frequency division duplex (FDD) multiple-input-multiple-output (MIMO) downlink (DL) channel Channel-State Information (CSI) acquisition is provided. A base station (BS) includes a transceiver configured to measure uplink (UL) sounding reference signals (SRSs) at a UL carrier frequency, using two polarization components of an antenna array of the BS, and a processor configured to determine a quantity of propagation paths between the BS and a user equipment (UE), for each of the determined propagation paths, extract propagation parameters from the UL SRS measurements, for each of the determined propagation paths, predict a downlink (DL) channel based on the extracted propagation parameters and a DL carrier frequency, and generate a precoding channel matrix for the UE by summing the predicted DL channels for each of the determined propagation paths and for each of the two polarization components of the antenna array of the BS.
