    The uniformity of high-intensity electromagnetic radiation field is mainly realized by multiple tests at a single point presently, which will inevitably lead to measurement errors due to the time-varying characteristics of the radiation signal itself. Moreover, the method of multiple tests at a single point greatly increases the test time and lowers the test efficiency. To solve these problems, a device realizing multi-points test was designed. The test area can be adjusted automatically. The simulation results show that the device can meet the 9-point uniformity test of radiation field in the range of 500 mm×500 mm-1500 mm×1500 mm. In the 1000 mm×1000 mm test area, the experimental verification was carried out for the two frequency points of 1.35 GHz and 2.88 GHz. The experiment shows that the designed test device can meet the 9-point automatic test requirement of high-intensity radiation field uniformity, which greatly improves the test efficiency and automation.
