Problems solved by technology

However, this antenna system has the following significant defects: the horizontally polarized antennas and vertically polarized antennas in the antenna unit are arranged orthogonally, resulting in a complex and loose structure of the entire antenna system, and each horizontally polarized antenna, each vertically polarized The coupling phenomenon between the antennas is more obvious
However, the increase in the number of antennas will also inevitably bring about interference caused by coupling between antennas

Abstract

The invention provides a bipolar antenna system, comprising at least one antenna array, each of which comprises at least one vertical polarized antenna unit and at least one horizontal polarized antenna unit arranged in the same plane, wherein respective vertical polarized antenna units and horizontal polarized antenna units comprise a printed circuit board and at least one dipole antenna elementetched on the printed circuit board, the printed circuit boards are also etched with antenna connection wires and antenna feed holes, and respective dipole antenna elements are connected to the antenna feed holes after being connected in parallel via the antenna connection wires. Compared with the antenna system in the prior art, the bipolar antenna system can not only provide horizontal polarizedand vertical polarized RF links with main beam radiation characteristics, but also ensure that the coupling interference between the RFs is maintained at a low level.

Description

technical field [0001] The invention relates to the field of antennas, in particular to a bipolar antenna system. 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 energy of the electromagnetic wave to generate a tiny voltage, and sends the voltage to the receiver Zoom in. [0003] Antennas are an essential part of any device that uses radio. It is widely used in systems ...
