Title:
RECTANGULAR SHAPED ARRAY ANTENNA AND INDOOR BASE STATION
Document Type and Number:
WIPO Patent Application WO/2021/135401
Kind Code:
A1
Abstract:
The present invention relates to a rectangular shaped array antenna. In a 3×3 matrix, directional patterns of two opposite radiating units at the beginning and end of the same row are superimposed, and a recess is filled by means of an intermediate radiating unit, so that a roughly square directional pattern can be obtained. Similarly, three radiating units in the same column can also form a similar directional pattern, thereby implementing three-dimensional square beam coverage. Furthermore, a guide sheet can narrow a main beam and increase the directionality of the radiating unit, so that a beam falling effect can be effectively improved and sidelobe suppression can be reduced, and finally, the purposes that the waveform of the main beam is in a three-dimensional square shape on main coverage and a lobe can quickly fall off outside a half-power angle are achieved. Moreover, the rectangular shaped array antenna has a simple structure and only requires as few as nine radiating units, and therefore, miniaturization can be implemented. In addition, the present invention further provides an indoor base station.
