High-frequency and low-frequency combined multi-frequency antenna array

Abstract

The invention relates to a high-frequency and low-frequency combined multi-frequency antenna array. The high-frequency and low-frequency combined multi-frequency antenna array comprises a low-frequency array composed of low-frequency vibrators and a first high-frequency array, a second high-frequency array and a third high-frequency array which are each composed of high-frequency vibrators. The high-frequency and low-frequency combined multi-frequency antenna array is characterized in that the middle of an antenna is provided with a double-frequency array which is formed by coaxially nesting the low-frequency array and the first high-frequency array, the second high-frequency array and the third high-frequency array are distributed at the two sides of the double-frequency array in a shoulder-by-shoulder and staggered mode, and the spacing distance among the high-frequency vibrators in the second high-frequency array is equal to that among the high-frequency vibrators in the third high-frequency array. According to the high-frequency and low-frequency combined multi-frequency antenna array, high gain, multiple frequency bands, high isolation and high reliability of the antenna are achieved on the premise that the size is small, and a new array antenna array arrangement scheme is provided for achieving the section coverage purposes of achieving station antenna coverage, high-quality communication and data transmission ratio, saving station space, increasing customer volume and the like.

Description

technical field [0001] The invention relates to a multi-frequency antenna array with combination of high and low frequencies, including the dipole arrangement of single-frequency, double-frequency and multi-frequency array antennas. Background technique [0002] In recent years, with the increase of mobile communication network standards, in order to save site and antenna resources, reduce the difficulty of property coordination, and reduce investment costs, multi-frequency array antennas with co-site and co-location have become the first choice for network construction. And in the existing wireless communication system, MIMO (Multiple-Input Multiple-Output) antenna technology is an important key technology to improve the quality and efficiency of mobile communication. The use of MIMO technology can greatly increase the capacity of the channel and improve the efficiency of the channel. Reliability, reduce bit error rate. [0003] However, with more and more frequency bands ...

Problems solved by technology

Although the shoulder-to-shoulder scheme has good symmetry in the pattern and relatively small size, it is difficult to guarantee the miniaturization of the whole machine if this scheme needs to realize four-band or even five-band antenna arrays.
