Abstract

Certain aspects of a method and system for an antenna architecture for multi-antenna orthogonal frequency division (OFD) based systems are disclosed. Aspects of one method may include communicating data in a radio frequency (RF) system comprising a plurality of antennas, via at least one polarized antenna that is orthogonally polarized with respect to adjacent polarized antennas. The plurality of coherently polarized antennas may be placed at a particular distance from each other.
