Title:
ARRAY ANTENNA AND MANUFACTURING METHOD FOR ARRAY ANTENNA
Document Type and Number:
WIPO Patent Application WO/2024/113192
Kind Code:
A1
Abstract:
An array antenna and a manufacturing method for an array antenna, for use in estimating a large number of DOAs. The array antenna comprises N array elements arranged in the same direction, N being an integer greater than or equal to 3. The distance between an i-th array element among the N array elements and a reference position in the direction is Mi times the unit length, i being any integer ranging from 1 to N. The N array elements have the same half-wavelength, and the unit length is a positive integer multiple of the half-wavelength. The N array elements have one-to-one correspondence to N positive integers, any two positive integers among the N positive integers are mutually prime numbers, Mi is a product of N-1 positive integers, and the N-1 positive integers are integers other than the positive integer corresponding to the i-th array element among the N positive integers. In this case, compared with conventional coprime array antennas, the distance between array elements of the array antenna is further increased, and the array elements are set more sparsely, such that the array antenna can be equivalent to a linear array having more array elements, such as a linear uniform array antenna, so as to estimate a large number of DOAs.
