Apple Anechoic Chamber Facilities

Apple showed a group of journalists around their Anechoic Chamber facilities. There are articles about the visit at Engadget, Macworld, New York Times and Techcrunch. Normal folks can learn a little from those articles about how antenna design is done. Antenna folks can get jealous and wish they had access to so many chamber.

Most large wireless companies have similar facilities, though most are not anything like as big. The photos show an ETS tapered chamber and a Satimo SG chamber. I commissioned an ETS 8600 in a previous job.

I don’t know what type the enormous cylindrical chamber pictured at the start of the New York Times article is. I’ve never seen a chamber like that before. It seems to have a series of range antennas in a ring around the wall.
