What are the most important impedance matching techniques to use in high-frequency PCB design?
Matching is very important to make sure your design will present optimal performance in the desired frequency range. In high frequency applications, the design of the PCB traces, dielectric material properties, and manufacturing tolerances such as copper roughness, trace etching and microwave glass weave are some aspects that needs to be considered to avoid unexpected surprises.

What are some effective ways to teach electronic engineering to undergraduate students?
The combination of theory, lab, and simulation is extremely valuable. Students can learn the theory, simulate their ideas to see if they make sense, and then test in the lab to actually and learn all concepts. Besides circuit simulation tools such as SPICE based, it is also important to simulate 3D geometries (PCB traces, antennas, filters, cables) to understand concepts especially related to microwave, RF, antennas. Most of the 3D field solver vendors such as Ansys provides free of charge student version so any student can download and try their ideas.

How can you design a PCB for high-frequency applications with minimal electromagnetic interference?
Also, today we have many PCBs with antennas, especially on IoT and consumer devices. Pay attention when routing critical nets close to antennas as the digital signals can desense the antenna radios and the antenna can induce noise into the signals, decreasing the overall performance of the system.
