Claim:
1. A coupled antenna apparatus, comprising: a first radiator element comprising a closed structure, the closed structure comprising a conductive ring-like structure; one or more second radiator elements that are disposed proximate to the first radiator element, at least one of the one or more second radiator elements being coupled to a first ground point; and a third radiator element that is disposed proximate to the one or more second radiator elements, the third radiator element being coupled to a feed port and a second ground point; wherein the first radiator element, the one or more second radiator elements and the third radiator element are not in galvanic connection with one another; wherein the conductive ring-like structure comprises one or more protruding conductive portions that are configured to optimize one or more operating parameters of the coupled antenna apparatus; wherein the one or more protruding conductive portions outwardly project from an external perimeter of the conductive ring-like structure; and wherein the conductive ring-like structure as well as the one or more protruding conductive portions comprises a floating structure that is free from both a galvanic coupling to a feed structure and a ground structure.
