1. 21. Evaluation, Optimization and Characterization of Miniaturized Triple Band Antennas for Wi-Fi 6 and Wi-Fi 6E

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

   Author : Muzi Cheng; [2022]
   Keywords : Antennas; Wi-Fi 6E; Radiation; Resonance; Tuning; Antenner; Wi-Fi 6E; Strålning; Resonans; Tuning;

   Abstract : Antenna is a key component in wireless devices such as cell phones, laptops and smartwatches. With the new generation of Wi-Fi technology: Wi-Fi 6E coming out, 1200MHz bandwidth from 5.925GHz to 7.125GHz is freed for use. READ MORE

3. 22. Design and Evaluation of a Novel Conveyor Utilizing a Screw Mechanism to Move Objects With Integrated Racks

   University essay from KTH/Mekatronik

   Author : Måns Nilsson; Mathias Nils Edvin Nordqvist; [2021]
   Keywords : Screw Conveyor; Intralogistics; Material Handling; Thread Meshing; Worm rack drive; Brushless motor; Skruvtransportör; Intralogistik; Materialhantering; gängingrepp; Snäckskruv och kuggstång; borstlös motor;

   Abstract : Intralogistics, or material handling, traditionally use roller or chain conveyors to moveo bjects and goods in factories and warehouses. One negative aspect of the traditional types of conveyors is that they are expensive, as they are comprised of many moving parts. READ MORE

4. 23. Efficiency verification of an electromechanical linear actuator

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Ingela Råberg; [2021]
   Keywords : Efficiency; Linear actuator; Modelling; Romax; Linjärt ställdon; Modellering; Romax; Verkningsgrad;

   Abstract : Cascade Drives has developed an electromechanical linear actuator with a patented feature which allows for load sharing between multiple pinions interacting on the same rack. This arrangement has proven resilient for shock loads, and allows for compact gearbox designs with very high load rating. READ MORE

5. 24. "Resonance frequency, Q-factor, coupling of a cylindrical cavity and the effect on graphite from an alternating electric field".

   University essay from Uppsala universitet/Fasta tillståndets elektronik

   Author : Jakob Gölén; Simon Persson; [2021]
   Keywords : Q-factor; Resonance frequency; Cavity; Microwaves; Heating; Q-faktor; Resonansfrekvens; Kavitet; Mikrovågor; Uppvärmning;

   Abstract : The purpose of this project was to investigate a cylindrical cavity resonator and use microwaves to heat up a material in the cavity. This was done by measuring the Q-factor and the resonance frequency of the cavity, both with and without material inside. READ MORE

6. 25. Look2Hook : The Impact of Menu Design and Input Device on Gaze-based Menu Selection

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