    Abstract: Aspects of the subject disclosure may include, for example, a polarization shifter including a lower substrate having disposed thereon first and second transmission lines for coupling to a feed network, an upper substrate having disposed thereon third and fourth transmission lines for respective communicative coupling to orthogonally-polarized elements of a radiating element, and a dielectric layer residing between the lower substrate and the upper substrate, the upper substrate being configured to mechanically couple to the radiating element, the dielectric layer coupling the first transmission line with the third transmission line and coupling the second transmission line with the fourth transmission line, the upper substrate being rotatable relative to the lower substrate to effect polarization adjusting for the radiating element to facilitate avoidance of interference or passive intermodulation (PIM). Other embodiments are disclosed.

    Abstract: Aspects of the subject disclosure may include, for example, obtaining data regarding interference originating from one or more interference sources, and electronically rotating polarizations of signals relating to crossed-dipole radiating elements of an antenna system, the antenna system operating in multiple frequency bands, the electronically rotating being performed for a select number of frequency bands of the multiple frequency bands and facilitating mitigation of the interference. Other embodiments are disclosed.
