Abstract: —A design approach for decoupling closely separated antennas is discussed. This design methodology is particularly useful when the available real estate is very limited, and modifying the ground plane is not a viable practical option- a situation that is typically encountered when designing smartphones. In addition, the design guidelines are applicable for multi-element arrays, resulting in the possible realization of large compact arrays, which is desirable for saving chipset cost when targeting mm-wave applications.
