Title:
ANTENNA, ANTENNA ARRAY, AND COMMUNICATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/223118
Kind Code:
A1
Abstract:
Provided in the present application are an antenna, an antenna array, and a communication apparatus, by means of which more degrees of freedom and antenna ports are expected to be constructed while the dimensions of an antenna panel are limited. The antenna comprises: four mutually independent feed points; and four spiral arms corresponding one to one with the four feed points, each spiral arm being connected to a corresponding feed point. The spiral end of each spiral arm can use an open-circuit branch structure to be connected between feed points corresponding thereto, and/or the tail end of each spiral arm can be coupled to a parasitic patch, and/or the spacing w between two adjacent spiral arms meet: w≤λ/10, wherein λ is the operating wavelength. By means of the foregoing design, the degrees of freedom of four ports can be provided, and the bandwidth of an antenna can also be widened. When the dimensions of an antenna panel are limited, the foregoing helps to improve system throughput.
