[0010] However, this coupling and fastening structure presents the disadvantage that a screw-based fastening device still needs to be used to ensure fastening reliability, especially to prevent the plug from rotating and falling out of the hole
Also, this assembly is detrimental from the point of view of the coupling surface

Embodiment Construction
[0045] exist figure 1In the depicted embodiment of the invention, a radiating element 1 is shown comprising a foot 2 supporting at least one dipole 3, and a reflector 4 to which the radiating element 1 is fastened by means of a dielectric part 5 superior. The dielectric part 5 comprises a base 6 mounted under a rod 7 carrying a protrusion 8 forming a hook, the periphery of which is cut so as to form a slightly curved flap 9 . The base 6 of the dielectric part 5 is applied to the rear surface 10 of the reflector 4 . The reflector 4 comprises a hole 11 through which the rod 7 is inserted. These holes 11 are only of the exact size required to insert the rod 7 which is mounted under its protrusion 8 . In the present case, the lower part of the foot 2 of the radiating element 1 comprises a recess 12 constituting a recess onto which the protrusion 8 hooks in order to hold the radiating element 1 .
[0046] The dielectric part 5 is made of a dielectric material that gives it some...

Abstract
The invention relates to a billboard antenna comprising a flat conductive medium comprising at least one opening, at least one radiating element including a leg with a dipole mounted thereupon and a device for coupling and attaching the radiating element on said medium. The device for coupling and attaching the radiating element, including a leg with a dipole mounted thereupon, on the medium comprises a dielectric component including a base that is larger than the opening made in said medium, at least one rod rigidly connected to the base and projecting in a direction perpendicular to the plane of the base through the opening of the medium suitable for the rod to pass therethrough, at least one projection arranged on the end of the rod suitable for engaging with the radiating element to hold said element. The device also includes a dielectric layer arranged between the radiating element and the conductive medium to avoid any direct contact.
Description
technical field [0001] The invention relates to the field of telecommunication antennas emitting radio waves in an ultra-high frequency field by means of radiating elements. The invention relates more particularly to a device which enables fast, reliable and low-cost coupling and fastening of a radiating element to a flat metal support during antenna assembly. [0002] In addition, it also relates to an antenna comprising such a device and a method for assembling such an antenna. Background technique [0003] The construction of the antenna includes the step of mechanically fastening its components to each other. Today, most antenna manufacturers use a mechanical assembly consisting of a chassis forming a central mechanical shaft to which all other components are fastened, such as radiating elements, power dividers , phase shifters, reflective walls, parasitic elements, etc. Once all the elements have been assembled around the chassis, the assembly is surrounded by a rado...
