  1. 1. 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

  2. 2. An investigation on the possibility for bandwidth improvement of dielectric antennas via modification of their geometry

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

    Author : Nandan Dutta Chaudhury; [2020]
    Keywords : Multifunctional antenna array; AESA; Additive manufacturing; Stereolithography; Ultra-wideband antenna; Dielectric antenna; Embedded DRA; PSF; Multifunktionell antenngrupp; AESA; Additiv tillverkning; Stereolitografi; Ultrabredbandig antenn; Dielektrisk antenn; Inbäddad DRA; PSF;

    Abstract : The dielectric antenna is an interesting alternative to a metallic antenna. This is mainlydue to its low manufacturing cost and the possibility to fabricate complex antennageometry with the aid of additive manufacturing (AM). Sophisticated AM technologyprovides new degrees of freedom in shaping the outer and inner geometry of antennas. READ MORE

  3. 3. Wireless electrocardiogram based on ultra-wideband communications

    University essay from Uppsala universitet/Signaler och System

    Author : Maria Toll; [2019]
    Keywords : UWB; ECG; EKG; ultra-wideband; electrocardiogram; ultra wideband; radio communication; Decawave; DW1000; IoT; internet of things; Android; IEEE 802.15.4-2011;

    Abstract : The goal for this master thesis is to develop a prototype that uses ultra-wideband (UWB) communications to wirelessly transfer electrocardiogram (ECG) data from an ECG measurement unit to an Android device (smartphone or similar) which is used to process and display the ECG signals. The prototype should consist of two hardware nodes; (1) Node one having a ECG measurement unit (an AD8232 single lead heart rate monitor), an UWB communication module (a Decawave DWM1000 module) and a microcontroller (an Arduino DUE); and (2) Node two having an Android device (an Android smartphone), an UWB communication module (a Decawave DWM1000 module) and a microcontroller (an Arduino DUE).

    University essay from Uppsala universitet/Signaler och System

    Author : Mattias Flodén; [2019]
    Keywords : ;

    Abstract : In this thesis an electrocardiography (ECG) prototype is developed that wireless transfer the ECG measurements to an Android smartphone. The prototype consist of two printed circuit boards (PCBs), an Android smartphone and an automatically tunable notch filter. READ MORE

  5. 5. Estimation of Orientation in a Dual-Tag Ultra Wideband Indoor Positioning System

    University essay from Uppsala universitet/Fasta tillståndets elektronik; Uppsala universitet/Fasta tillståndets elektronik

    Author : Oscar Johansson; Lucas Wassénius; [2019]
    Keywords : UWB; Ultra Wideband; Indoor Positioning;

    Abstract : In this report the feasibility of using a dual-tag setup in an indoor positioning system was investigated. The reason for the dual-tag setup was to be able to estimate both position and orientation. The system was designed using UWB-technology, with an time of flight trilateration algorithm to calculate the position. READ MORE
