- the third shoulder 142 is included, in the direction Z, between the crown 144 and the second end 122. In the direction Z, the third shoulder 142 is located at a fourth distance H4 from the second end 122. In Figure 12, the fourth distance H4 is equal to the first distance H1.
- the axial cavity 134 extends between the second end 122 and the first shoulder 142.
- the axial cavity 134 is adapted to receive the first rectilinear portion 1 14 by a translation along the Y direction.
- the axial cavity 134 is parallelepipedal.
- the three pairs of sides of the axial cavity 134 are respectively perpendicular to the X, Y and Z directions.
- the axial cavity 134 has a first width 11 greater than or equal to the third diameter D3.
- the first width 11 is equal to the third diameter D3.
- the lateral cavity 136 is between the second shoulder 142 and the third shoulder 144.
- the lateral cavity 136 is adapted to receive the second rectilinear portion 1 16 by a translation along the Y direction.
- the lateral cavity 136 is parallelepipedal.
- the three pairs of sides of the axial cavity 134 are respectively perpendicular to the directions X, Y and Z.
- the lateral cavity 136 has a second width 12 greater than or equal to the fourth diameter D4.
- the second width 12 is equal to the fourth diameter D4.
- the ring 144 is cylindrical with a circular base, Z axis.
- the ring 144 has a seventh diameter D7.
- the seventh diameter D7 is greater than or equal to the sixth diameter D6. In FIG. 12, the seventh diameter D7 is smaller than the first diameter D1.
- the crown 144 is delimited in the direction Z by the second shoulder
- the crown 144 In the direction Z, the crown 144 has a third width L3.
- the third width L3 is greater than the fourth diameter D4.
- the operation of the antenna structure 10 according to the fourth embodiment is similar to the operation of the antenna structure 10 according to the first embodiment.
- the straightness of the dielectric device January 12 is fixed by the construction of the radome 16 and the positioning cavity 1 10. No specific tool is therefore used to fix the straightness of the dielectric device 12.
- the dielectric device 1 12 is fixed relative to the radome 16, in the absence of a force exerted by an operator. This means that, when the dielectric device 1 12 is in its inserted position, the positioning cavity 1 10 exerts on the dielectric device a clamping force greater than the sum of the weights of the dielectric device 1 12 and the elementary antenna 12.
- the radome 16 it is possible to pre-assemble a plurality of elementary antennas 12 and dielectric devices 1 12 to the radome 16 before attaching the radome 16 to the housing 22.
- Each of the elementary antennas 12 can be removed or replaced easily.
- the mounting of the antenna structure 10 is thus simplified.
- the elementary antenna 12 is inserted into the dielectric device 1 12.
- the dielectric device 1 12 is then inserted into the positioning cavity 1 10, then the radome 16 is fixed to the housing 22.
- the dielectric device 1 12 then extends through the coaxial access port 106 without being in contact with the transceiver surface 14.
