Description of impactModern wireless communication circuits and systems have become very complex and multi-functional. Radios will become even more complex, with tens of antennas in small devices that are adaptive, for example, in frequency, beam direction and polarization, in systems like massive MIMO (multiple-input and multiple-output) and cognitive radio. The number of circuit components and mixed mode signaling is increasing and, therefore, challenging simulation methods and models. High-speed communications and accurate sensing require increased bandwidth, which is only available at millimeter wave (mm-wave) and terahertz (THz) frequencies; the same applies to many other applications, such
as THz imaging, wireless sensing and identification, which are finding completely new concepts.
Strong, high-quality doctoral education is the key issue in solving the increasingly complex problems of future wireless technology. During the past 25
years, some 125 doctors in related areas, such as antennas and propagation, mm-wave and THz technology, and integrated circuit design, have graduated from our unit. These alumni are now in leading positions in telecommunications-related industries, academia (including several professors), and in the public sector, such as the European Space Agency (ESA). We have received the status of ESA external competence center (MilliLab), and we were awarded the Center of Excellence (CoE) in Research by the Academy of Finland (SMARAD).
