The invention relates in part to a folded dipole having a dipole axis and a pair of arms which together have a profile which is concave on one side and convex on the other when viewed along the dipole axis. The dipoles may be arranged as a dipole box around a central region, typically in a generally circular or square configuration. Further elements may be placed in the dipole box or in the gaps between dipole boxes. The antenna may be a single-band antenna, or a multi-band antenna with the further elements operating in a different frequency band to the dipole boxes. The further elements may be concentric dipole boxes. The invention is particularly suited for use in a cellular base station panel antenna. A novel coaxial to microstrip transition is also described.

Dipole antennas and coaxial to microstrip transitions

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.

Antenna element, feed probe; dielectric spacer, antenna and method of communicating with a plurality of devices

There is provided a cellular antenna allowing mechanical azimuth adjustment in combination with adjustment of one or more other antenna attribute such as electrical down tilt, electrical beam width or electrical azimuth adjustment. An integrated control arrangement is provided which can utilise either serial, wireless or RF feed lines to convey communications. A multiband embodiment provides azimuth adjustment for both bands by utilising mechanical and electrical azimuth adjustment. Systems incorporating such antennas and methods of controlling them are also provided.

Cellular antenna and systems and methods therefor

A base station antenna system producing a beam, includes an array antenna rotatably mounted with respect to an antenna support so as to permit azimuth steering of the antenna beam and an azimuth position rotation arrangement configured to rotate the array antenna with respect to the antenna support about an antenna axis. The rotation arrangement further includes an actuator mounted on the antenna support having an operator adapted to move linearly along an operator motion axis parallel to the antenna axis when the actuator is energized. A motion converter is coupled between the actuator and the array antenna, wherein linear movement of the operator along said operator motion axis produces rotary movement of the antenna about the parallel antenna axis.

Base station antenna rotation mechanism

A method and apparatus are provided for constructing a multi-band antenna (). The method includes the steps of providing a plurality of combination-type dipole assemblies (, FIG.) each defined by a box-type dipole array () disposed coaxially within a circular-type dipole array (), disposing the plurality of combination-type dipole assemblies along a substantially straight line () over a ground plane () and disposing a plurality of crossed-type dipole antenna arrays along the substantially straight line in alternating order with the plurality of combination-type dipole assemblies.
