Document Type and Number:
WIPO Patent Application WO/2024/016665
Kind Code:
A1
Abstract:
The present disclosure relates to an antenna feed source and an antenna comprising the antenna feed source. The antenna feed source comprises a waveguide tube, a dielectric support block and a reflective surface, wherein a relatively small end of the dielectric support block is connected to the waveguide tube, and the other end of the dielectric support block that is opposite the relatively small end has a sunken inner surface; the dielectric support block has a longitudinal axis, and the inner surface is symmetrical about the longitudinal axis; the reflective surface is attached to the inner surface; in a longitudinal section of the dielectric support block, a section of the inner surface on one side of the longitudinal axis at least has a first spline section, a second spline section and a third spline section; the distance between the second spline section and the longitudinal axis is greater than the distance between the third spline section and the longitudinal axis, and is smaller than the distance between the first spline section and the longitudinal axis; and first, second and third included angles respectively between tangent lines of the first, second and third spline sections and the longitudinal axis are respectively within first, second and third angle ranges, and the minimum angle in the second angle range is greater than the maximum angle in the first angle range and the maximum angle in the third angle range.
