Embodiment Construction

[0058] refer to Figure 1~Figure 5 , the present invention provides a method for testing the performance parameters of active antennas. According to the characteristics that the uplink and downlink of active antennas cannot be reversed, the present invention designs different platforms to test the uplink and downlink respectively, so as to accurately measure the uplink and downlink of active antennas. Antenna pattern and gain.

[0059] Specifically, the object of the present invention is accomplished through the following steps:

[0060] The uplink pattern test method includes the following steps: signal generation, a fixed-frequency continuous wave signal is generated by a signal source 1; signal amplification, through a corresponding frequency band power amplifier 2 for linear amplification; remote transmission, through a fixed horn antenna 3 in a microwave anechoic chamber 4 terminal transmission; through the anechoic chamber, the signal passes through the interior of the ...

Abstract

The invention provides a test method for the performance parameter of an active antenna. According to the characteristic that an uplink and a downlink of the active antenna can not be reciprocal, in the invention, different platforms are designed for respectively testing the uplink and the downlink so as to accurately measure the uplink and the downlink antenna directional diagrams and the gain of the active antenna. The test method for the uplink and the downlink directional diagrams and the gain of the active antenna is a novel test method, which is provided for the active antenna and developed on the basis of a traditional passive antenna. Because no effective measuring method is designed for the uplink and the downlink directional diagrams and the gain of the active antenna at present, the method in the invention can be used for accurately measuring the uplink and the downlink directional diagrams and the gain of various active antennas through the matched design of related parts at the far end, the inner part and the near end of a microwave darkroom and the real-time record control of a control computer, thereby favorably promoting the development of the active antenna.

Description

technical field [0001] The invention relates to the field of mobile communication base station antennas, in particular to a new testing method for an active antenna uplink and downlink pattern and gain. Background technique [0002] At present, the development of mobile communication is making great strides forward. After the issuance of domestic 3G licenses, the three major operators are vigorously laying 3G networks; looking at the world, 4G commercial networks have been opened, and more and more 4G networks will definitely be invested in the future. Construction; In a word, the mobile communication closely integrated with people's life is developing at a rapid speed. [0003] However, the construction of the base station system as the core of mobile communication faces many problems. First of all, in order to achieve the best coverage effect, the distance between the computer room and the passive antenna needs to be as short as possible, which puts forward high requi...
