Abstract
Cellular antennas having a mutual coupling can be isolated by the generation of an additional current path along a ground plane. A first antenna element can resonate at a resonance that interferes with and is mutually coupled to a second antenna element operating in a same frequency range, such as a low band frequency range. One or more parasitic scattering elements can generate the additional current path between the two antennas and isolate the two antennas from one another. A parasitic scattering element can comprise two capacitors that alter a radiation pattern of one of the antennas and decrease a correlation between both antennas.
