1. 1. Antenna Arrays for Dual-Frequency Harmonic Radar Application

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Venkatesh Raja; Mohammad Zafar Mohammad; [2023]
   Keywords : Technology and Engineering;

   Abstract : The aim of this thesis is to design two patch antenna arrays for dual-frequency harmonic radar application, one for the transmitter and the other for the receiver. The arrays are used to track the Bogong moth that migrates from the countryside to the Australian Alps during spring. READ MORE

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

   University essay from Linköpings universitet/Elektroniska Kretsar och System

   Author : Natachai Terawatsakul; [2023]
   Keywords : ;

   Abstract : 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

4. 3. Telemetry System for Real-Time Monitoring of a Formula Student Electric Vehicle

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Simon Richter; Joachim Larsson; [2021]
   Keywords : Telemetry; RF; CAN; 868-GHz radio; PCB design;

   Abstract : Real-time monitoring of vehicle data during testingcan drastically cut down on test times as well as improve thequality of testing by facilitating the implementation of run-timecompliance verification with expected model behavior, along withanomaly detection in both hardware and software. By providinga wireless communication link between vehicles and a monitoringbase station, this project aims to build the groundwork formore sophisticated testing proceedings in the future. READ MORE

5. 4. Geodesic Lens Antenna for sub-THz Imaging

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Joan Mitjans i Blasco; [2021]
   Keywords : ;

   Abstract : The Millimiter Wave (mmW) frequency band, characterized by a high atmospheric attenuation and wide available bandwidth has become of big interest for high accuracy radar imaging applications. The continuous development of the Monolithic Microwave Integrated Circuit (MMIC) technology yields to the appearance of different commercial-off-the-shelf (COTS) radar transceivers at that frequency band, where the antennas are fully integrated into the chip.

6. 5. A Study of Multipath Propagation and Doppler Effect at 24GHz ISM band

   University essay from Högskolan i Gävle/Elektronik

   Author : Shaikh Masud Rana; [2020]
   Keywords : Multipath Propagation; Doppler Effect; 24GHz; ISM Band;

   Abstract : The wideband channel has been analyzed at the University of Gävle by using millimeter-wave (mm-Wave) frequency for improving the fifth-generation (5G) in Radio-frequency (RF) characterization. The proposed mm-Wave frequency is 24GHz, which is carried out from measurement testbed at the Robotics Lab. READ MORE
