Abstract (en)
[origin: EP3316397A1] The invention provides a fixed multi-beam helical antenna stereoscopic array, comprising helical antenna units and a frustum structure which comprises a top surface and a plurality of side surfaces, the upper ends of the side surfaces are connected with the edge of the top surface, the side edges of the adjacent side surfaces are connected, and the top surface and side surfaces are provided with helical antenna units respectively, wherein, the top surface of the frustum structure is in the shape of a regular polygon, and the side surfaces are in the shape of isosceles trapezoids. Each helical antenna unit is isolated by a beam isolation plate, and the helical antenna of the helical antenna unit is mounted on the dielectric plates. The helical antenna has a folding and unfolding function, and the effective control over the pitch and rigidity of the helical antenna is achieved by flexible support wires and a pitch fine-adjustment device. The invention realizes antenna beam pointing deflection by the stereoscopic frustum structure, so as to realize a beam coverage in the airspace in a wider field of view, without using the phase-shifting feeding network; mutual-coupling among the antenna units is reduced and the frustum structure is downsized by the beam isolation plate, and the antenna stereoscopic array is better from the electrical performance, cost and weight.
