Enhancing Laboratory Experience Using 3D-Printing Technology in Microwave and Antenna Education [Educator's Corner]

The development of modern wireless techniques has resulted in a need for more trained RF engineers. For college students majoring in microwaves and antennas, practical training is essential to understanding abstract electromagnetic theories and to cultivating their engineering skills [1]. However, the traditional fabrication methods for microwave devices used in university labs aren’t appropriate for undergraduate students because of their inflexibility, high cost, and use of harmful chemicals.
