Quadrupolar Antennas and Quadrupolar Multiple Antenna Arrays

Abstract

The invention discloses a quadrupolar antenna vibrator, a quadrupolar antenna and a quadrupolar multi-antenna array. Among them, four polarized oscillators are included in the four-polarized antenna oscillator, the midpoints of the four polarized oscillators coincide, the polarization direction of the first polarized oscillator is the horizontal direction, and the polarization direction of the second polarized oscillator is in the horizontal direction. Vertically, the angle between the polarization direction of the third polarizer and the horizontal direction is 45 degrees, and the angle between the polarization direction of the fourth polarizer and the horizontal direction is -45 degrees. By integrating four polarized elements with different polarization directions into one antenna element, the width of the antenna is reduced, and the requirement of horizontal isolation between two columns of dual-polarized antennas is also avoided, so there will be no Additional space requirements are put forward for the base station antenna to ensure the smooth deployment of LTE and 4G networks.

Description

technical field [0001] The invention relates to the communication field, in particular to a quadrupolar antenna dipole, a quadrupolar antenna and a quadrupolar multi-antenna array. Background technique [0002] At present, the mobile communication network has been developed to the third generation (The Third Generation, 3G for short), and the 3G network has been deployed and commercialized on a large scale around the world. With the continuous popularization and promotion of data services and mobile Internet, the International Telecommunications Standards Organization is formulating technical standards such as Long Time Evolution (LTE for short) and 4G to meet the continuous development of network technology and service capabilities. Since multiple input and multiple output (Multiple Input and Multiple Output, referred to as: MIMO) technology can make full use of independent spatial propagation paths to improve network service rate and link performance, MIMO technology has b...

Problems solved by technology

At the same time, in actual engineering, it is also necessary to ensure that the downtilt angles of the two dual-polarized antennas that are horizontally isolated are consistent, and because the horizontally isolated MIMO antenna increases the number of physical antennas on the base station sky, it will increase the coordination between the operator and the base station site property. Difficulty, so the MIMO antenna in the above horizontal isolation mode has certain difficulties in the actual construction and deployment of the network

[0006] Because people are now paying close attention to the electromagnetic radiation problem, it is difficult to increase the number of independent physical antennas at the site of many base stations, and at the same time, it is difficult for many base stations to have enough space to ensure the horizontal isolation distance of multiple antennas, especially when the number of MIMO antennas requires Scenes with 4 or more roots

Therefore, the solution of using multiple physical antennas is not conducive to the deployment of LTE and 4G networks
