Far-Field, Anechoic Chamber, Compact and Near-Field Antenna Measurement Techniques

Course Description

Master the state-of-the-art far-field, anechoic chamber, compact, and near-field antenna measurement techniques! In this course, you will also learn antenna measurement facility characterization and compensation techniques, as well as microwave holography. You will examine theory and optimal application of each technique, concentrating on basic concepts, design, procedures, and application. Your focus will be on antenna measurements in the high frequency, very high frequency, ultra high freqiency, microwave, and millimeter-wave frequency ranges. Plus, you will visit NSI-MI Technologies’ compact range and near-field demonstration facilities.

Due to minimum enrollment requirements to hold a course, we ask that you register as early as possible. View our terms and conditions for further information. If you have specific questions or requirements, please contact the course administrator.
