Antenna measurements through planar near field apparatus: An educational paradigm linking electromagnetic theory, sampling techniques, and FFT

Abstract

Integrating antenna pattern measurements in the classroom offers many captivating insights about electromagnetic fields that is visually appealing to young scientists and students. In particular, the planar near-field measurement techniques allow instructors to connect to fundamental knowledge about antennas. Challenging concepts become immediately a hands-on discussion while providing students an important application of fundamental electrical engineering and electromagnetic theories. Our table-top bipolar apparatus also brings out a discussion on the challenges of measurements at high frequencies, such as mmWaves, where cable movement and flexing can cause significant errors. This paper suggests planar near-field measurements as an educational paradigm linking electromagnetic theory, sampling techniques, and FFT.
