Antenna device and antenna array

Abstract

The invention discloses an antenna device and an antenna array. The main content is that the antenna device includes three antenna oscillators fixed onto a supporting part, wherein a vertical distance between the radiation center of each antenna oscillator fixed onto the supporting part and a mirroring reflection ground plate is 1 / 5[lambda] to 2[lambda]; any two antenna oscillators fixed onto the supporting part mutually intersect at right angles; and an angle value of an included angle formed by a polarization direction and a horizontal direction of any different antenna oscillator is identical. Each antenna oscillator is connected with a feed network board through a core wire of a coaxial cable. The feed network board is used for independently adjusting amplitude and phase of a transceiving signal on each antenna oscillator. The three-polarization antenna device is applied to a communication network built by using MIMO technology, is convenient for address site selection and installation, and can help to improve the covering capability of network signals, raise broadband data service processing level and increase spectrum resource utilization rate.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to an antenna device and an antenna array. Background technique [0002] With the development of communication technology, 3G, 4G and future communication networks will have higher and higher requirements on the channel capacity of communication systems and the utilization rate of spectrum resources. [0003] MIMO (Multiple-Input Multiple-Out-put) technology refers to the use of multiple transmitting antennas and receiving antennas at the transmitting end and receiving end respectively, and signals are transmitted and received through multiple antennas at the transmitting end and receiving end, thus Improve the quality of service (eg bit error rate, data rate or QoS) for each user. [0004] However, existing communication antennas are divided into two types: one is a single-polarization antenna; the other is a dual-polarization antenna. The so-called single-polarized ...
