Claim One:
1. A self-grounded antenna arrangement, comprising: at least one central portion arranged in a first plane and configured to operate as a ground; and at least one arm section associated with the at least one central portion, each arm section tapering toward a respective end tip, comprising an electrically conducting material, being adapted to form a transition from the at least one central portion, being bent backward toward the at least one central portion by more than 180°, and having its end tip approaching the at least one central portion on a side thereof at an opening in the at least one central portion, the end tip further being adapted to be connected to a feeding port, a respective feeding port being provided for each arm section, whereby the arrangement has a mixed functionality of a curved monopole antenna and a loop antenna; wherein the arrangement comprises at least two first arm sections; tips of the at least two first arm sections approach the at least one central portion on a same side of the at least one central portion at a distance from each other; the feeding ports for each of the at least two arm sections are substantially uncoupled such that their far-field patterns are substantially orthogonal in either polarization, direction, or shape; and the first arm sections are diametrically symmetrically disposed for reducing coupling between the feeding ports.
