Description
In this study, we developed a non-reflecting absorbing structure (film) for fast OTA and reference levels measurements above 6 GHz. Infrared (IR) imaging is used enabling non-perturbing, fast, and broadband 2D measurement with sub-mm resolution, in the far as well as in the near field. The absorbing film is designed to minimize perturbance of the antenna under test, which enables measurements in conditions similar to free-space. The thermal properties of the film are optimized to enhance the SNR thus enabling measurements of low-power wireless devices. The method was experimentally validated for different antenna types demonstrating excellent agreement with numerical simulations.
