Definitions
- a known solution consists in associating a high band antenna type band antenna antenna with a dipole-type low band antenna, using the metal plane of the high band antenna as a reflective plane.
- the dipole type antennas have a large footprint.
- the invention proposes a low band antenna capable of operating in a first frequency band centered on a first low frequency frequency, comprising at least a first radiating element, able to be positioned on a high band network antenna operating in a a second frequency band centered on a second frequency called high frequency, said high frequency being strictly greater than said low frequency, so as to form a two-band frequency antennal system, said high band antenna comprising a network of second radiating elements providing each electromagnetic radiation.
- each second radiating element comprises a support for the first radiating element or elements in material capable of propagating the electromagnetic radiation of each second radiating element without disturbance, said support having a predetermined thickness, less than or equal to a maximum value equal to the maximum distance over which each second radiating element radiates in tubular mode;
- said at least one first radiating element is composed of a metal mesh.
- the first radiating element 14 is positioned, in the view of FIG. 4, above the second radiating elements 18 of the high band antenna.
