Abstract
The embodiments herein use polarization diversity between antennas where the antennas for one cell are, e.g., horizontally polarized and antennas for the other cell are vertically polarized. In one embodiment, the antennas for a macro cell are vertically polarized while micro cell antennas are horizontally polarized. In one example, the micro cell antennas are printed antennas that form a loop that is co-planar with the magnetic fields generated by the macro cell antennas when transmitting. Because the magnetic fields are co-planar (rather than orthogonal) to the current flowing through the loop in the micro cell antenna, the effect of the electromagnetic signals emitted by the macro cell antenna is reduced. This may permit dual radio network devices to have improved performance when operating simultaneously—e.g., when the macro cell radio is transmitting and the micro cell radio is receiving at or near the same frequency band.
