| Abstract | (54) METHOD AND APPARATUS FOR ANTENNA Publication Classification RADATION CROSS POLAR SUPPRESSION (51) Int. Cl. H04B 700 (2006.01) (76) Inventors: David Edwin Barker, Stockport (52) U.S. Cl. ........................................................ 455/507 (GB); David Sam Piazza, San Jose, CA (US); Stephen Thomas (57) ABSTRACT Newbold, Holmer Green (GB) Cross-polar discrimination (XPD) of a dual orthogonal cross polarised antenna is maximized via a cross-coupling network (21) Appl. No.: 13/429,042 between base station MIMO branches prior to connection to the base station antenna. In one embodiment, across coupling (22) Filed: Mar. 23, 2012 network combines each MIMO branch signal with an attenu ated phase reversed (phase shifted) copy of the other MIMO branch signal. The amount of attenuation for each branch is equivalent to the cross polar suppression required for each (60) Provisional application No. 61/467,915, filed on Mar. antenna array. The cross-coupling can be applied at different 25, 2011. stages of signal processing within a base station. Related U.S. Application Data |
