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

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

   Författare :Venkatesh Raja; Mohammad Zafar Mohammad; [2023]
   Nyckelord :Technology and Engineering;

   Sammanfattning : 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. LÄS MER

3. 2. 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.

4. 3. Investigation of Hybrid Simulation Methods for Evaluation of EMF Exposure in Close Proximity of 5G Millimeter-Wave Base Stations

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

   Författare :David Anguiano Sanjurjo; [2020]
   Nyckelord :5G; base station; EMF exposure; hybrid simulation method; millimeter wave;

   Sammanfattning : With the emergence of Fifth Generation (5G) mobile networks, the employment ofhigher frequencies in the millimeter-wave (mmWave) range and the realization of agreat number of beams in 5G radio base stations (RBS) make the electromagnetic (EM)simulation of RBS products very costly in terms of hardware and time requirements.In order to compute the electromagnetic field (EMF) exposure in close proximity of theRBS, more efficient simulation methods are required.

5. 4. Radio Based User Presence

   Master-uppsats, KTH/Radio Systems Laboratory (RS Lab)

   Författare :Ana Rosalía Santamaría Portolés; [2015]
   Nyckelord :RFID; HF; RFID limitation; reading distance limitation; SIP; user detection; user location; RFID; HF; RFID begränsning; läsavstånd begränsning; SIP; användardetektering; användarens plats;

   Sammanfattning : While radio frequency identification tags (RFIDs) have been widely used for identifying objects (and some people), their primary use has been for access control, inventory, and other similar purposes. In this thesis we will use the detection of an RFID to indicate that a user is present in a given location. LÄS MER
