Being able to use the programming language and being able to design hardware are my great strengths. It is also my strength that I can use various simulation tools. I worked as an undergraduate researcher at Incheon National University for 1 year and 6 months. Through my undergraduate researcher activities, I acquired great antenna design skills using 3d EM simulation tool CST. I went to graduate school to acquire more diverse skills. I use AWR and ADS, which are 2D EM simulation tools to combine the antenna and circuit. Currently, I am learning PCB design.
