Title:
COMMON-CALIBER DUAL-BAND FUSION ANTENNA STRUCTURE AND FUSION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/116719
Kind Code:
A1
Abstract:
Disclosed in the present invention is a fusion method for a common-caliber dual-band fusion antenna. The method relates to the technical field of antennas and solves the problems of radiation performance and impedance performance severely worsening and common-caliber integration being unable to be achieved due to mutual coupling when two antennas operating at adjacent frequency bands are completely arranged in a common-caliber manner. By means of the method, a first dielectric substrate is arranged directly above a floor; a second dielectric substrate is arranged between the floor and the first dielectric substrate; a first meta-surface structure, a first radiation ring, a second radiation ring and a second meta-surface structure are arranged in a first quadrant to a fourth quadrant of the top surface of the first dielectric substrate; a fourth radiation ring, a fourth meta-surface structure, a third meta-surface structure and a third radiation ring are arranged in a first quadrant to a fourth quadrant of the bottom surface of the first dielectric substrate; first high-frequency oscillators are symmetrically arranged on the top surface of the second dielectric substrate; and second high-frequency oscillators are symmetrically arranged on the bottom surface of the second dielectric substrate. Further disclosed in the present invention is a common-calibere dual-band fusion antenna structure. By means of the present invention, effective decoupling is achieved by arranging the meta-surface structures.
