The MTT-S Education Committee–Promoting education for all–2022

One of key roles of the IEEE Microwave Theory and Technology Society (MTT-S) Education Committee is to help with the career development of students and professionals at different stages in their careers. First, the committee aims to develop multiple education resources, such as monthly MTT-S webinars and the Distinguished Microwave Instructors (DMI) program. Next, the committee shares these resources through different activities and platforms, including undergraduate scholarships and graduate fellowships, as well as many student design competitions at MTT-S-sponsored conferences. Student newsletters feature review technology articles and announcements regarding the application deadlines of scholarships/fellowships as well as some important conferences. Finally, the committee works hard to increase the regional presence of the MTT-S through a wide range of activities.ITESO, A.C

A novel 24 GHz circularly polarised metasurface rectenna

A novel 24 GHz circularly polarised metasurface rectenna for wireless power transmission is designed in this study. Based on experimental measurements and retro‐simulation, an effective approach is proposed to extract the parasitic parameters of a Schottky diode. A highly efficient millimetre wave rectifier with a measured efficiency of 63% is constructed based on the exact equivalent circuit parameters of a diode. A circularly polarised metasurface antenna is adopted as the receiving antenna, and the gain is enhanced by introducing metal vias around the metasurface. The antenna and the rectifier are connected directly via a microstrip line. Measurements show that the metasurface antenna has a gain of 11.3 dBic and an axial ratio of 2.5 dB at 24 GHz. The measured conversion efficiency of the rectenna reaches 63% at 300 Ω load when the input power is 15.2 dBm. The rectenna has the advantages of low profile, which can be conformal to the electrical equipment
