Microwave darkroom description: This is the microwave darkroom set up by our company in Shenzhen. This microwave darkroom belongs to a far-field measurement system. The size of the darkroom is 7.0m x 4.0m x 3.0m, and the size of the quiet zone is 15cm x 15cm x 15cm. Fig. 1 shows the instrument setup and network analyzer connection diagram in the microwave darkroom. The distance from the transmitting antenna (the transmitting antenna model used in this darkroom is TRCLPA0860 700MHZ-6GHZ) to the antenna under test (AUT) is 1.35 meters. The antenna under test is placed on a rotating platform. By controlling the rotation angle of the turntable, a rough and relatively accurate measurement can be made on the antenna under test. Place the antenna to be tested on a rotating table and measure the 360-degree field strength data of each plane (ZY plane and ZX plane). Then replace the antenna to be tested with a standard dipole antenna (the standard dipole antenna model used in this darkroom is TRCAD series dipole antenna 800MHz~2500MHz) and measure its 360-degree field strength data to convert the gain standard value. The gain value and radiation pattern of the antenna to be tested can be obtained through the conversion of formula 1.
