Title:
WIDE SCANNING PATCH ANTENNA ARRAY
Document Type and Number:
WIPO Patent Application WO/2023/085840
Kind Code:
A1
Abstract:
The disclosure relates to a wide scanning antenna array. The technical result consists in increasing the beam scanning range of the antenna array and the operating frequency range, simplifying the design of the antenna array and reducing losses. An antenna array is provided. The antenna array includes a plurality of antenna array elements. Each antenna array element of the plurality of antenna array elements includes a main printed circuit board (PCB) over which a middle layer and an additional PCB are arranged. A first patch element is disposed at the main PCB, and a second patch element is disposed at the additional PCB. The antenna array element further includes a cavity in the middle layer to reduce coupling between the antenna array element and at least another antenna array element of the plurality of antenna array elements. The cavity in the middle layer includes a hole that supports coupling between the first patch element and the second patch element. The main PCB, the middle layer and the additional PCB are interconnected by means of a no galvanic connection.
