Abstract

This application discloses feeding devices, antennas, and electronic devices. In one implementation, a feeding device comprises a phase shifter, a combiner, and a jumper component, wherein the phase shifter has a first cavity, the combiner has a second cavity adjacent to and connected to the first cavity, and the phase shifter is connected to the combiner through the jumper component.

First claim

What is claimed is:

1. A feeding device for wireless communications, comprising:
a phase shifter, a combiner, and a jumper component, wherein
the phase shifter has a first cavity, the combiner has a second cavity adjacent to and connected to the first cavity, and the phase shifter is connected to the combiner through the jumper component.

2. The feeding device according to claim 1 , wherein the phase shifter is a first phase shifter, the feeding device comprises at least a second phase shifter, and wherein the at least the second phase shifter shares the first cavity with the first phase shifter or each of the at least the second phase shifter has a cavity different from the first cavity.

3. The feeding device according to claim 2 , wherein each of the at least the second phase shifter has a cavity different from the first cavity, and wherein first cavity and the cavity corresponding to each of the at least the second phase shifter are placed side-by-side in a horizontal direction or a vertical direction.

4. The feeding device according to claim 1 , wherein the combiner is one of one or more combiners comprised in the feeding device, and each of the one or more combiners comprises a cavity that comprises more than one chamber, each of the more than one chamber comprises more than one tributary unit,
an i th tributary unit of the j th combiner has a one-to-one correspondence with an i th chamber, and wherein a j th output end of an i th phase shifter is connected to the i th tributary unit of the j th combiner through the jumper component.

5. The feeding device according to claim 4 , wherein the more than one chamber is placed side-by-side in a horizontal direction or a vertical direction.

6. The feeding device according to claim 1 , wherein the first cavity and the second cavity are integrally formed.

7. The feeding device according to claim 1 , wherein the jumper component comprises:
a metal sheet and a plug connector, wherein the plug connector is fastened at an edge of the metal sheet,
the metal sheet is welded to the phase shifter, and the plug connector is plugged to the combiner.

8. The feeding device according to claim 7 , wherein the metal sheet and the plug connector are integrally formed.

9. The feeding device according to claim 1 , wherein the feeding device is comprised in an antenna.

10. The feeding device according to claim 1 , wherein the feeding device is comprised in an electronic device.

11. The feeding device according to claim 1 , wherein the jumper component comprises:
a metal sheet and a plug connector, wherein the plug connector is fastened on an edge of the metal sheet, the metal sheet is welded to the combiner, and the plug connector is plugged to the phase shifter.
