Problems solved by technology

In this case, the added radiating element has to be fed through the patch element, which is not easy
However, the upper radiating element cannot use a shared reflector to generate its radiation pattern, but must use the tiled radiating element located below it as a reflector, with the disadvantage of reduced surface area

Embodiment Construction

[0041] exist figure 1 , 2 In the first embodiment shown in a and 2b, the dual-polarized radiating element 1 is formed by two half-wave dipoles 2, and each dipole includes a conductive feeder 3. The dipole 2 is supported by a shared support 4 fixed to a reflector 5 . The radiating element 1 is constructed by forming the shared support 4 into a cylindrical shape. The cylindrical support 4 thus obtained is then placed on a shared planar reflector 5 with a plurality of radiating elements 1 in a perpendicular manner.

[0042] In this example embodiment, the dipoles 2 are printed on the first outer surface 6 of the shared support 4 . Each dipole 2 is fed by a wire 3 located on the second inner surface 7 of the support 4 . Of course, it is possible to print the dipoles on the inner surface and the feed lines on the outer surface. The conductive feed 3 is, for example, a "microstrip" printed directly on the support 4 . This shared support 4, whose circumference is about 2 wavel...

Abstract

A dual-polarization radiating element for a multiband antenna comprises a support with a high dielectric constant whose shape is roughly cylindrical, having an axis of revolution, at least a first and a second pair of dipoles printed on a first surface of the support, the dipoles of the first pair being roughly orthogonal to the dipoles of the second pair, and conductive lines, to feed each dipole, printed onto a second surface of the support. The support is placed on a flat reflector, with the cylindrical support's axis of revolution being perpendicular to the plane of the reflector.

Description

[0001] Cross References to Related Applications [0002] This application is based on French Patent Application No. 1054150 filed May 28, 2010, which is hereby incorporated by reference in its entirety and which claims priority under 35 U.S.C. §119. technical field [0003] The invention relates to the field of multiband antennas for base stations for radio communications. Most of these antennas are generally of the "panel" type and include normally aligned dual polarized radiating elements. Background technique [0004] A dual polarized radiating element generally consists of 2 dipoles (or dipole systems) crossing each other with 45° orthogonal polarizations, one generating the signal of the first polarization (-45°) and the other generating the second polarization signal (+45°). The techniques used to construct the radiating elements are varied. [0005] The main conditions for radiating elements such as those used in panel antennas for base stations include, in partic...
