Title:
WAVE ABSORPTION AND TRANSMISSION INTEGRATED DEVICE, AND RADOME
Document Type and Number:
WIPO Patent Application WO/2020/019675
Kind Code:
A1
Abstract:
The present invention provides a wave absorption and transmission integrated device, and a radome. The wave absorption and transmission integrated device comprises: a wave transmission structure body comprising a first substrate, and metal patch units respectively located on opposite surfaces of the substrate; and a wave absorption structure body arranged on the wave transmission structure body and comprising a first wave absorption unit and a second wave absorption unit perpendicular to each other. The first wave absorption unit or the second wave absorption unit comprises: a second substrate; and multiple metal sections and multiple stop bands, which are all located on a surface of the second substrate, wherein the multiple metal sections and the multiple stop bands are connected in an alternating manner to form an absorption ring, and the metal patch units are arranged to be perpendicular to an absorption ring of the first wave absorption unit and an absorption ring of the second wave absorption unit. The device can achieve a high wave transmission rate for an L wave band and a high absorption rate for a Ku wave band in a wide range of angle domains, thereby effectively improving the working environment of radio equipment.
