ABSTRACT:
A multiband base station antenna for communicating with a plurality of terrestrial mobile devices is described. The antenna including one or modules, each module including a low frequency ring element; and a high frequency dipole element superposed with the low frequency ring element. The element includes a ground plane; and a feed probe directed away from the ground plane and having a coupling part positioned proximate to the ring to enable the feed probe to electromagnetically couple with the ring. A dielectric clip provides a spacer between the feed probe and the ring, and also connects the ring to the ground plane. An antenna element is also described including a ring, and one or more feed probes extending from the ring, wherein the ring and feed probe(s) are formed from a unitary piece.
