Evaluation of a magnetic near field scanner

Traditionally, the measurement of antenna performance often required significant capital outlay on anechoic test chambers and associated test equipment. A novel device manufactured by Canadian company Emscan that can perform some of these measurements in a bench-top environment may offer a solution. A study was undertaken into the performance of the Emscan near-field scanner. Comparisons with measurements taken in anechoic chamber and theoretical models using CST microwave studio are used in the evaluation of the scanner as well as measurements of repeatability and accuracy.
