Abstract

A first antenna element is indirectly coupled to communication signals via a coupler that is located within a same volume of a body. A second antenna element is proximate to and adjacent the first antenna element. The first antenna element is configured to operate in a first frequency range and the second antenna element is configured to operate within a subset of the first frequency range concurrent with or simultaneously to the first antenna element. The coupler can operate to couple multiple antenna elements operating at different frequencies within the same volume of the body.
