Title:
ELECTROMAGNETIC STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2023/221193
Kind Code:
A1
Abstract:
Disclosed is an electromagnetic structure, which belongs to the field of communication antennas. The electromagnetic structure comprises: a Vivaldi antenna and a decoupling structure, wherein the decoupling structure is arranged between a left arm and a right arm of the Vivaldi antenna, and one end of the decoupling structure extends to a radiation end of the Vivaldi antenna, and the other end thereof extends to a feed position of the Vivaldi antenna. The decoupling structure suppresses, by means of destroying a surface wave which is coupled to the Vivaldi antenna, the process of a surface wave being converted into transverse electromagnetism; and the decoupling structure is only present in the interior of the antenna and does not occupy an extra space beyond the antenna. The electromagnetic structure is independent, and the decoupling structure only affects a Vivaldi antenna which is coupled to, and does not generate a relationship with other antennas in an array. Therefore, massive MIMO array decoupling can be performed, and higher isolation can be realized at close range.
