Title:
ANTENNA UNIT AND ANTENNA ARRAY
Document Type and Number:
WIPO Patent Application WO/2019/114740
Kind Code:
A1
Abstract:
The present application provides an antenna unit and an antenna array. The antenna unit comprises M layers of cross-shaped metal patches, M layers of dielectric substrates, and a metal ground layer, wherein M is an integer greater than 1. Moreover, the ith layer of dielectric substrate is provided between the ith layer of cross-shaped metal patch and the (i+1)th layer of cross-shaped metal patch. The ith layer of cross-shaped metal patch, the ith layer of dielectric substrate, and the (i+1)th layer of cross-shaped metal patch are laminated in sequence, wherein i is an integer ranging from 1 to M-1. The M layers of cross-shaped metal patches, the M layers of dielectric substrates, and the metal ground layer are laminated in sequence. The antenna unit provided by the present application and the antenna array consisting of the units provided by the present application may have good polarization characteristic, a relatively wide operation bandwidth, and good phase-shift characteristics.
