Abstract

A support piece comprises: a first support section configured in the shape of a plate, and a plurality of second support sections; every second support section in the plurality of second support sections is set on the outside of the first support section and is bent relative to the first support section; every second support section comprises at least one support structure. At least a portion of the support structure of the at least one support structure is configured to support a first dipole arm, and at least a portion of the support structure of the at least one support structure is configured to support a second dipole arm; a second arm section on the outside of the first dipole arm is bent relative to the first arm section on the inside toward a first side of the first support section to support the dipole arm; a second arm section on the outside of the second dipole arm is bent relative to the first arm section on the inside toward a second side of the first support section opposite to the first side.

First claim

That which is claimed is:

1. A radiating element, comprising:
a support piece comprising a first support section and first through fourth second support sections that are each positioned outwardly of the first support section and bent relative to the first support section, each of the first through fourth second support sections comprising at least one support structure;
first through fourth dipole arms that each comprise a first arm section and a second arm section positioned outwardly of the first arm section, where every second arm section comprises a mounting structure,
wherein the second arm section of the first dipole arm is bent relative to the first arm section toward a first side of the first support section such that the first and second arm sections of the first dipole arm lie in different planes,
wherein the second arm section of the second dipole arm is bent relative to the first arm section thereof toward a second side of the first support section that is opposite the first side such that the first and second arm sections of the second dipole arm lie in different planes,
wherein a first portion of the at least one support structure of each of the first through fourth second support sections is configured to match the mounting structure of the first dipole arm, and a second portion of the at least one support structure of each of the first through fourth second support sections is configured to match the mounting structure of the second dipole arm.

2. The radiating element of claim 1 , wherein the first support section has a plate-like shape.

3. The radiating element of claim 1 , wherein each second support section is bent toward the first side of the first support section.

4. The radiating element of claim 1 , wherein the at least one support structure of each of the first through fourth second support sections comprises a support bayonet, a support screw hole, or a support protrusion.

5. The radiating element of claim 1 , wherein the at least one support structure of each of the first through fourth second support sections comprises a first support and a second support structure, where the first support structure is positioned forwardly of the second support structure.

6. The radiating element of claim 5 , wherein the first second support section comprises a first rib, a second rib, a third rib, a fourth rib, a fifth rib, a sixth rib, and a seventh rib set in sequence and at angles with each other,
wherein the first support structure comprises two support bayonets formed at the connection of the second rib with the first rib and the third rib and at the connection of the sixth rib with the fifth rib and the seventh rib respectively, and
wherein the second support structure comprises a support bayonet formed at the connection of the fourth rib with the third rib and the fifth rib.

7. The radiating element of claim 1 , wherein the first support section comprises four first support sub-sections that extend in respective first through fourth directions, wherein each of the first through fourth second support section is set on the outside of a respective one of the first support sub-sections, and wherein the first direction is opposite the second direction, the third direction is opposite to the fourth direction; moreover, and the first direction is perpendicular to the third direction.

8. The radiating element of claim 7 , wherein each first support sub-section includes at least one through opening.

9. The radiating element of claim 7 , wherein the four first support sub-sections encircle a feed opening.

10. The radiating element of claim 1 , wherein the support piece further comprises a plurality of support beams that extend between the first support section and the corresponding second support sections.

11. The radiating element of claim 10 , wherein the support piece further comprises a plurality of support legs that are positioned on the second side of the first support section.

12. The radiating element of claim 11 , wherein the support piece is a monolithic structure.

13. A radiating element that is configured to be mounted on a reflector, the radiating element comprising:
a first dipole that includes a first dipole arm and a second dipole arm;
a second dipole that includes a third dipole arm and a fourth dipole arm, the second dipole extending perpendicularly to the first dipole,
wherein each of the first through fourth dipole arms comprises a plurality of widened conductive segments that are connected by a plurality of narrowed conductive segments, and each of the first through fourth dipole arms has a base that is proximate a center of the radiating element and a distal end that is opposite the base, and
wherein the distal end of each of the first through fourth dipole arms is bent either rearwardly or forwardly with respect to a plane that is parallel to the reflector such that the distal end and a proximal end of each of the first through fourth dipole arms lie in different planes with respect to each other.

14. The radiating element of claim 13 , wherein the distal end of each of the first through fourth dipole arms comprises a narrowed conductive segment.

15. The radiating element of claim 13 , wherein the distal end of each of the first through fourth dipole arms is bent at least 30 degrees with respect to the plane that is parallel to the reflector.

16. The radiating element of claim 13 , wherein the distal end of each of the first through fourth dipole arms is bent about 90 degrees with respect to the plane that is parallel to the reflector.

17. The radiating element of claim 13 , wherein the distal ends of at least some of the first through fourth dipole arms are bent rearwardly and the distal ends of at least some of the first through fourth dipole arms are bent forwardly.

18. The radiating element of claim 13 , wherein one of the narrowed conductive segments of each of the first through fourth dipole arms is bent with respect to the plane that is parallel to the reflector.

19. The radiating element of claim 13 , further comprising a support piece that includes a first support section and first through fourth second support sections that are each positioned outwardly of the first support section and bent relative to the first support section, each of the first through fourth second support sections comprising at least one support structure.
