1. 21. Automating the Part Identification Method of Automotive Assembly Lines Through RFID Technology

   Master-uppsats, KTH/Industriella produktionssystem

   Författare :Felix Buchner; [2022]
   Nyckelord :RFID; General Assembly; Part identification; Traceability; Automotive industry; Genealogy; Barcode scan; Vehicle scan; RFID; allmän montering; Identifiering av delar; Spårbarhet; Fordonsindustrin; Genealogi; Skanning av streckkoder; Skanning av fordon;

   Sammanfattning : Barcode scanning has been used for many decades in the assembly process to identify individual parts. Besides the fact that scanning is a non-value-adding operation, it also is prone to error. It cannot beensured with certainty that the scanned part will be the part installed. LÄS MER

3. 22. 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.
