Title:
BIFOCAL COMBINED PARABOLIC ANTENNA
Document Type and Number:
WIPO Patent Application WO/2024/031929
Kind Code:
A1
Abstract:
Disclosed in the present invention is a bifocal combined parabolic antenna, comprising a bifocal combined paraboloid, a first dual-polarization feed source and a second dual-polarization feed source, wherein the bifocal combined paraboloid has a first focal point and a second focal point; the distance from the first focal point to the mean axis of the bifocal combined paraboloid is equal to the distance from the second focal point to the mean axis of the bifocal combined paraboloid; and phase centers of the first dual-polarization feed source and the second dual-polarization feed source are provided on a connecting line of the first focal point and the second focal point. In the present invention, a 4×4 high-gain MIMO antenna is realized by using a bifocal combined paraboloid having a relatively high aperture reuse rate, and the polarization diversity and spatial diversity effects thereof are similar to those of two 2×2 high-gain MIMO antennas, which are stacked for application, such that the device usage amount and space occupation can be reduced by 50% compared with those in the prior art.
