Abstract

The invention discloses an antenna system, comprising a substrate, and a plurality of antenna units which are arranged in a predetermined geometric pattern and are connected to the substrate. Each antenna unit includes a horizontally polarized antenna and a vertically polarized antenna. The horizontally polarized antenna or the vertically polarized antenna of the antenna unit is stimulated based on instruction and the antenna type signal adopting the antenna system, and thereby better wireless link can be provided to the communication device.

Description

technical field [0001] The present invention relates to the field of antennas, and more particularly to an antenna array that is electronically controlled to form a desired antenna pattern, wherein two independently polarized antenna elements can be electrically controlled to form the same main beam radiation characteristic. Background technique [0002] The antenna system is essential in the composition of the communication system. In existing wireless communications, a single antenna is used for the transmitting source and the receiving end respectively. In physics, an antenna is an electrical device that provides conversion between electrical energy and radio frequency electromagnetic waves, and is usually used in a wireless transmitter or receiver. When transmitting, the wireless transmitter sends an oscillating radio frequency current to the antenna, and the antenna converts it into electromagnetic waves to radiate; when receiving, the antenna intercepts a part of the...
