## Abstract In this paper, we apply microwave holography to infrared (IR) thermal images of electromagnetic (EM) fields to measure nearβfield and farβfield radiation patterns of antennas. The phase of the field is retrieved from IR thermograms (magnitudeβonly thermal images of the field) measured i
