Title:
SLOT ANTENNA SUBARRAY, ANTENNA ARRAY, AND BASE STATION
Document Type and Number:
WIPO Patent Application WO/2021/088157
Kind Code:
A1
Abstract:
The utility model relates to the technical field of communications, and in particular, to a slot antenna subarray, an antenna array, and a base station. The slot antenna subarray comprises a conductive cover, a feed plate, a plurality of vibrators, and at least two isolation plates, wherein the conductive cover is provided with an accommodating groove having an opening at one side; the feed plate and the plurality of vibrators are provided in the accommodating groove; the two isolation plates are provided between two adjacent vibrators at intervals; and an isolation belt is formed between the two isolation plates that are provided at intervals. The slot antenna subarray, the antenna array, and the base station of the utility model are optimized in structural design, low in costs, simple in structure and easy in large-scale production, satisfy the array forming requirements of Massive MIMO, have excellent co-polarization isolation and hetero-polarization isolation, and optimize the problem of serious mutual coupling of the antenna array.
