Abstract

See full text

An apparatus includes a first reactive component coupled between a first antenna and a second antenna in a multi-band antenna system. The apparatus further includes a first operation circuit coupled to the first reactive component. The first reactive component and the first operation circuit together form a signal path to enable signal flow between the first and the second antennas when the first and the second antennas are operating at a first frequency. The first operation circuit disables signal flow along the signal path when the first and the second antennas are operating at a second frequency.
