1. 1. Extending Wireless Power Transfer Range for Self-Powered Micro Devices with mm-size Antenna

   Master-uppsats, Linköpings universitet/Elektroniska Kretsar och System

   Författare :Natachai Terawatsakul; [2023]
   Nyckelord :;

   Sammanfattning : 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. LÄS MER

3. 2. A Modular Approach to Design and Implementation of an Active GNSS Antenna

   Master-uppsats, Linköpings universitet/Fysik, elektroteknik och matematik; Linköpings universitet/Tekniska fakulteten

   Författare :Ulrik Hecktor; [2022]
   Nyckelord :GNSS; RTK; circular patch antenna; LNA; stacked patch antenna;

   Sammanfattning : This master’s thesis describes the design, implementation and testing of an active antenna intended for use with global navigation satellite systems. The active antenna is composed of two major parts, a dual-band circular patch antenna and a dual-band low-noise amplifier. To streamline the design process, a modular solution was adopted. LÄS MER

4. 3. Antenna Design and Link Performance Verification of Antennas for 5G mmWave Handheld Devices

   Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

   Författare :Vinodhini Mylai Chandrasekaran; Nikhila Chinnayanapalli Ravi; [2022]
   Nyckelord :Antenna Design; mmWave frequency; 5G; FEKO; Technology and Engineering;

   Sammanfattning : The purpose of the thesis is to design a new antenna system and to verify its link performance in 5G FR2 mmWave frequency for handheld devices to enable cellular communication. The main objective is to design an antenna primarily at 28GHz and 39GHz to enhance spectrum efficiency, along with improved transmission data rates, enabling new cases like Augmented Reality (AR), Virtual Reality (VR) and many more such applications.

5. 4. 3D-Printed Geodesic Luneburg Lens Antenna With Novel Patch Antenna Feeding

   Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Elin Berglund; Sandis Freimanis; [2021]
   Nyckelord :Luneburg lens; patch antenna; geodesic; transformation optics; 3D-printing;

   Sammanfattning : With the roll out of new technologies and the worldbecoming more connected, there is a rising demand for higherbandwidth and new frequency bands. To meet the demand,higher frequencies are used in new communication systems.Higher frequencies come with the need for new antenna designsand one promising type of antenna is the lens antenna.

7. 5. RTK GNSS

   Kandidat-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

   Författare :Stephanie Mirsky; [2021]
   Nyckelord :RTK GNSS; RTK; GNSS; NTRIP; Technology and Engineering;

   Sammanfattning : 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. LÄS MER
