Title:
DUAL-POLARIZED FILTERING ANTENNA UNIT AND DUAL-POLARIZED FILTERING ANTENNA ARRAY
Document Type and Number:
WIPO Patent Application WO/2022/242069
Kind Code:
A1
Abstract:
The present application relates to a dual-polarized filtering antenna unit and a dual-polarized filtering antenna array, and relates to the technical field of antennas. The dual-polarized filtering antenna unit comprises a metal substrate and a radiation layer, wherein a plurality of dielectric layers are arranged between the metal substrate and the radiation layer, each dielectric layer is provided with first via holes and second via holes, the first via holes and the second via holes are used for accommodating metal columns, the metal columns are used for transmitting current signals, the axes of the first via holes of the plurality of dielectric layers are parallel or overlap, and the first via holes of adjacent dielectric layers are electrically connected by means of a metal layer between adjacent dielectric layers.
