EM-lab seminar: Electrical small antennas, from mobile phones to implanted sensors

​Welcome to a seminar held by the Electromagnetics Laboratory (abbreviated EM-Lab) , which is an assembly of senior researchers and teachers with activities in the scientific field of electromagnetics. EM-Lab is hosted by the Department of Electrical Engineering at Chalmers.​  
Speaker: Professor Anja Skrivervik, Microwave and Antenna group, École Polytechnique Fédérale de Lausanne, Switzerland

Title: Electrical small antennas, from mobile phones to implanted sensors

Abstract: Electrically small antennas (ESAs) have been discussed since the early radio days, when all antennas were small compared to the wavelength. The boom of mobile phones triggered a second wave of intense research activity on these devices, which continues today where virtually everything has a wireless connection. This intense research activity has produced interesting and usefully results on the physical limitations of such antennas, design rules and optimal designs. Since the beginning of the century, the number of medical, sports, or security applications (to name just some of them) requiring implantable or wearable communication devices has grown at a high speed, launching the interest for wearable or implantable ESAs. Many interesting designs have been published to this date, but we only start understanding the fundamentals of such antennas. Neither physical bounds on their radiation characteristics nor optimal designs or design rules are yet available. In this contribution, I will highlight the main similarities and differences between classic ESAs and antennas for wearables and implants, illustrated by practical examples.
