Problems solved by technology

[0003] The arrangement of high and low frequency radiation units in the existing multi-frequency antenna cannot cover all the frequency bands of 3G and 4G, only the working frequency band of the low frequency radiation unit is 820Hz-960MHz, and the working frequency band of the high frequency radiation unit is 1710MHz-2017MHz( The frequency band involved in 3G) or 2575MHz-2635MHz (the frequency band involved in 4G), since the working frequency band of each radiating unit is used independently, if it covers most of the frequency bands of 3G and 4G at the same time, the volume of the antenna will Larger, unable to meet the requirements of miniaturization

Abstract

The invention discloses a multi-frequency common base station antenna comprising a reflection plate, a low-frequency radiating unit and a high-frequency radiating unit which are arranged on the reflection plate and a dual-frequency combiner which is connected with the high-frequency radiating unit. The dual-frequency combiner is connected with the high-frequency oscillators in the two arrays of the target high-frequency radiating unit in the high-frequency radiating unit in a one-to-one way to multiplex the high-frequency oscillators. The feeding end of the dual-frequency combiner is connectedwith the feeder network corresponding to the two frequency bands of the target high-frequency radiating unit. Therefore, the high-frequency oscillators are multiplexed by the dual-frequency combinerso as to realize a wider working frequency range without increasing the size of the reflection plate, and thus the volume and the size of the antenna are small and the antenna meets the requirements of miniaturization and multi-frequency of the antenna.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a base station antenna shared by multiple frequencies. Background technique [0002] With the rapid development of high-speed rail construction and mobile Internet of Things services, when users travel by high-speed rail, the demand for online entertainment and mobile office is increasing day by day, and the requirements for communication quality are also getting higher and higher. Due to high-speed movement and complex terrain conditions, the performance of the wireless channel changes drastically. The multipath effect and the influence of Doppler frequency shift cause the signal to fade, and it is easy to cause abnormal calls, handovers, and call drops. In addition, domestic site resources are becoming more and more tight, and operators are choosing antennas that are increasingly miniaturized and multi-frequency antennas are deployed at one time. [0003] The arra...
