Abstract: A dipole antenna comprises N dipole elements spaced along a dimension of the antenna, each dipole element including a pair of electrically conductive structures and 2N electronic networks each coupled to a corresponding electrically conductive structure of an associated dipole element to form N pairs of electronic networks wherein each electronic network includes a port. The electrically conductive structures are electrically isolated from one another.
