Description

OSCILLATOR ANTENNA GENERATED

The present invention relates to a device for receiving or transmitting electromagnetic waves up to the upper limit of the telecommunication frequencies.

Traditional oscillator antennas are Hertz dipoles using the natural free charges of the metal constituting the dipole, have low transmission power and limited domestic use because of their inefficiency or complexity to be deployed.

The device according to the invention overcomes these disadvantages. It comprises in fact according to a first characteristic, a generator of electrical charges making it possible to provide a large number of external free electrical charges in a configuration that is both filiform and bi-specific. This configuration, which is both filiform and bi-point-loaded, is transformed into a powerful dipole both electrical and magnetic in the presence of incident electromagnetic fields rendered stationary by a wave reflector. The re-emission of this electromagnetic dipole can then be easily picked up by a wave pick-up system.

According to particular embodiments: the electric charge generator may consist of a Hall generator in which the conductive or semiconductor material ends with a special eccentric end housing a configuration that is both filiform and bi-pointlike. - The wave reflector is a metal piece to reflect the waves. the wave pick-up system may be a conically shaped metal for directing the waves in a cable.

The accompanying drawings illustrate the invention:

Figure 2 shows in section, the wave pickup system.

Figure 3 shows in profile, the main functional device of the invention.

Figure 4 shows in section, the antenna as a whole.

Figure 5 shows in section, a variant in the external mounting of the antenna.

Figure 6 shows in profile, a variant of the electric charge generator.

With reference to these drawings, the main elements of the antenna are: the electric charge generator (FIG. 1) which can be composed of a magnet (4), a conducting or semi-conducting material (5) powered by a constant electrical voltage whose poles (6) and (7) are on this conductive or semiconductor material and which can end with a special eccentric end housing a filiform configuration (9) and a bi-point configuration (10). ) and (11). the wave pick-up system (FIG. 2) which can be composed of a metal cone (13), at the center of which is a wire (14) and which ends with a cable entry (15). The central wire (14) is held by a support (16) welded to the inlet of the metal cone. the wave reflector (3) shown in FIG.

The main functional device of the antenna (FIG. 3) consists of the electrical charge generator (1) disposed at one end of the wave reflector (3) and the wave pickup system (2), the metal cone ( 13) is welded to the other end of the wave reflector (3).

This main functional device of the antenna is sealed, as shown in FIG. 4, in a dielectric "housing" (17) which isolates it from the outside and whose second function is to maintain the internal cohesion of the main functional device. The functional device thus sealed is mounted on a mounting bracket (18) and (19), a variant of which is shown in FIG. 5, in order to fix the antenna to pick up the waves without disturbance.

It is established for the waves that come orthogonally on the surface of the reflector (3), a standing wave. The stationary wave thus established is the cause of oscillations of the large colony of free electric charges situated on the filiform (9) and bi-point (10) and (11) configurations of the special eccentric end of the conductive or semi-conductive material. conductor of the charge generator. This special eccentric end is therefore a powerful dipole both electrical and magnetic emitting in all directions and whose emissions are captured by the wave pickup system (2).

In the embodiment according to FIG. 4, a thin electrical insulator is established thanks to the dielectric "housing" on the one hand between the conductive or semiconductor material (5) of the charge generator and the wave reflector. (3), and on the other hand between the filamentary configuration (9) and the outer edge (8) of the conductive or semiconductor material. It can also be established an electrical insulation between the filiform configuration (9) and the bi-point configuration (10) and (11) which is the extension on either side of the ends of the conductive or semiconductor material (5). ). The fixing support comprises a carrying platform (19) and a tripod (18), a very flexible and highly adaptable part of the antenna, which can allow rotation in azimuth, in latitude and an elongation in height as well as the possibility of being fixed immobile. By way of nonlimiting example, the dielectric "housing" (17) representing the external form of the antenna will have dimensions of the order of 50 cm for the length, 5 cm for the width and 5 cm of thickness. The tripod of the mounting bracket could have a minimum height of 20 cm.

The device according to the invention is particularly effective for the reception and transmission of UHF frequencies as well as for satellite reception and transmission in all telecommunication domains. Its ease of deployment ensures extensive home use.
