Abstract

The invention discloses a long term evolution (LTE) antenna intelligent measurement system, which comprises an emitter subsystem, a rotary table subsystem, a radio frequency subsystem, a servo drive subsystem and a computer subsystem. The emitter subsystem comprises an emission polarization device. The rotary table subsystem comprises a seven-dimensional motion device, a locking device and a to-be-tested antenna mounting bracket. The radio frequency subsystem comprises a vector network analyzer and a multi-way switch. The servo drive subsystem comprises a servo driver and a multi-axis control card. The computer subsystem comprises a computer, a network card, a real-time controller (RTC), a control software and a data processing software. The servo drive subsystem is connected with the emitter subsystem and the rotary table subsystem at the same time. The computer subsystem is connected with the servo drive subsystem and the radio frequency subsystem at the same time. The antenna intelligent measurement system is fast in measurement speed and high in measurement precision. Meanwhile, the system can be used for the LTE antenna measurement during the development and production process.

Description

technical field [0001] The invention belongs to the technical field of antennas, and relates to an antenna measurement system, in particular to an LTE antenna intelligent measurement system. Background technique [0002] The antenna is the converter of the circuit signal of the communication equipment and the space radiated electromagnetic wave, and is an important part of the mobile communication system, and its performance directly affects the performance of the entire communication system. One of the key technologies adopted by the fourth-generation mobile communication is LTE technology. As LTE technology is applied to the terminal equipment of 4G system, the technical requirements of LTE antenna include broadband, multi-band and dual polarization. With the advent of LTE antenna, LTE antennas place high demands on the measurement system, while existing antenna measurement systems such as figure 1 ) mainly includes the transmitting device subsystem, the turntable subsyst...
