CTIA has specific requirements for 3 D antenna pattern measurements.
The specification for the test site is quite stringent. We built two specific chambers only for these measurements since we couldn’t meet the requirements in our regular EMC chamber.

I am asked to look into the capability to perfom this measurement. My questions are: 1. Is there any particular site/chamber requriement, such as a full anechoic chamber, etc.? 2. Is any particular instrument required in addtion to a spectrum analyzer/receiver and antennas for radiated emission measurement per FCC Part 15? You will also need a signal generator to provide a stimulus signal, usually into the antenna under test. This can usually be a simple CW source, and 0 dBm is usually quite adequate. This assumes a relatively simple antenna. If the antenna is active (like a phased array or synthetic aperture), then you will have to test the complete device with the antenna. 3. Is software/firmware available for antenna pattern measurement? 4. How to look for the labs that provide services for this measurement? Further definition of the antenna and desired test frequencies will help to narrow your selection of labs. Thank you and look forward to hearing from you.
