Title:
MILLIMETER WAVE ANTENNA ARRAY UNIT, ARRAY ANTENNA, AND COMMUNICATION PRODUCT
Document Type and Number:
WIPO Patent Application WO/2019/213878
Kind Code:
A1
Abstract:
The present application relates to a millimeter wave antenna array unit, comprising a grounding layer, a first dielectric layer, a first radiation patch, a second dielectric layer, and a second radiation patch. A first feed part is at least partly provided within the first dielectric layer, or within the second dielectric layer, or between the first and second dielectric layers. The first feed part is insulated from the first radiation patch, the second radiation patch, and the grounding layer. A second feed part is at least partly provided within the first dielectric layer, or within the second dielectric layer, or between the first and second dielectric layers. The second feed part is insulated from the first feed part, the first radiation patch, the second radiation patch, and the grounding layer. The first feed part and the second feed part respectively excite electromagnetic wave signals of two frequency bands to the first radiation patch and to the second radiation patch and generate two types of polarized electromagnetic wave signals on the first radiation patch and on the second radiation patch. Also provided in the present application are an array antenna and a communication product.
