1. Extending Wireless Power Transfer Range for Self-Powered Micro Devices with mm-size Antenna
University essay from Linköpings universitet/Elektroniska Kretsar och SystemAbstract : The primary challenge in expanding the wireless power transfer range for miniaturized self-powered micro devices is the limited RF energy harvesting due to the small effective area and low gain of the mm-sized antennas used in these devices. This thesis introduces a method for extending the distance between an external energy source antenna (TX) and a micro-device antenna (RX) to more than 10 cm. READ MORE

5. RTK GNSS
University essay from Lunds universitet/Institutionen för elektro- och informationsteknikAbstract : RTK GNSS is a way of deciding the position of a GNSS receiver with high precision. It should theoretically be possible to determine the position with the precision of a couple of centimeters. Traditionally the RTK GNSS system consists of a base station and a rover. READ MORE
