Abstract
An electromagnetic anechoic chamber includes a chamber, a test bench located in the chamber for supporting an electronic device, a horizontal high frequency antenna, a perpendicular high frequency antenna, a horizontal low frequency antenna, a perpendicular low frequency antenna, four directional filters, four relays, a mixer, and a receiver. The horizontal high frequency antenna, the perpendicular high frequency antenna, the horizontal low frequency antenna, and the perpendicular low frequency antenna are located around the platform, and electrically coupled to the directional filters. Each relay includes a first end connected to the mixer and a second end connected to the corresponding directional filter. The mixer is electrically coupled to the receiver. The mixer generates a composite signal. The composite signal is transmitted to the receiver. The receiver analyzes and displays whether the electronic device is qualified or not.
