Problems solved by technology

The antenna, radio frequency, and baseband of the fifth generation mobile communication system (5G) are integrated, and the antenna oscillator cannot work alone. In particular, 5G millimeter-wave devices are smaller and more integrated. It is becoming more and more difficult to conduct conduction tests on traditional radio frequency ports. It is more necessary to test the radiation characteristics of the whole machine through OTA (Over The Air)
However, in measuring the environmental impact of 5G communication equipment, especially high and low temperature tests, due to the limitations of OTA testing capabilities such as general environmental test chambers generally do not have internal electromagnetic wave absorption, and there is no effective electromagnetic wave penetration design in a certain direction, there is currently no Simple and feasible test method, there are serious deficiencies in the development and testing of communication equipment such as 5G
[0003] Faced with the demand for OTA testing of such a variety of communication equipment at high and low temperatures, traditional testing methods can no longer meet the needs of testing
