Abstract
Testing apparatuses, and methods for using such apparatuses to calibrate and test an antenna, include a chamber that includes a lining, the lining being made from a material that is absorptive to radiation at a test wavelength. An adjustable platform is positioned at a first side of the chamber, the adjustable platform being rotatable to change an orientation of a device under test. A probe is positioned at a second side of the chamber, opposite to the first side of the chamber, that measures electromagnetic radiation from the device under test. A vector network analyzer communicates with the device under test and the probe to determine calibration information for the device under test.
