Event Type: Workshop / Outreach
Date of Event: 20/01/2016
Following the trial run conducted earlier this month, SUTD IEEE-HKN today conducted the EM Workshop for 22 Anderson Junior College (AJC) students. These students were from the Science Club in their school, and they all share a strong passion in science and research.
The workshop, which covered the entire process of making a patch antenna, was kicked off by Prof. Shaoying’s short lecture on Electromagnetism and its importance.
The students then proceeded to design their patch antenna using a commercial software. Besides calculating the performance of the designed antenna, the software also allowed the students to visualize the propagation pattern of their antennas, as well as optimize certain design parameters to improve their performance. The lesson was conducted by our president Wei Jian, while other HKN members were on hand to provide guidance along the way.
After getting the antenna design completed on software, it was time to proceed to the actual fabrication. The fabrication was done in-house in SUTD’s Fab Lab, where there are two PCB prototyping machines which can be used to mill the patch antennas.
While at the Fab Lab, the students were also treated to a tour around the facility. The two-storey facility is home to a wide variety of fabrication and prototyping machineries, and it was an eye-opener for the students.
The final part of the workshop involves the testing of the fabricated antennas. Using a Virtual Network Analyzer (VNA), Prof Shaoying helped to quantify the performance of each antenna. She also conducted a series of simple experiments to illustrate how distance, direction and polarization can affect the transmission and reception of electromagnetic waves.
Besides teaching the AJC students about Electromagnetism, the workshop was also an opportunity for them to engage with the staff and students of SUTD, and to further their understanding of the university’s culture. The students ended the workshop with their self-fabricated antennas to boast as souvenirs.
A special mention to our lecturer Dr. Lee Chee Huei for his sharing on EM and SUTD’s pedagogy in today’s workshop! Also, we would like to thank our fellow coursemates in Stanley and Sabareesh for acting as both teaching assistants and tour guides for the event!
