  1. 1. Bladder Monitoring Using Ultra-Wideband Radar and Vivaldi Antenna

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi

    Author : Erica Jonsson; Attila Kovács; [2023]
    Keywords : UWB; Ultra-wideband; Vivaldi antenna; Bladder monitoring; Radar; Radar design; Ultra-wideband radar;

    Abstract : Millions worldwide cannot tell when their bladder is nearing total capacity. The catheter, a tube to empty the bladder, is a vital part of life for many people. A catheter is, however, not a comfortable option, and it is the most common cause of infection in people staying in hospitals. READ MORE

  3. 2. Scann Loss Reduction on Phased Array Antenna

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

    Author : Wanyu Zhang; [2022]
    Keywords : Phased Array Antenna; Vivaldi Antenna; Scan Loss; Coverage Angle; Sub-array; Embedded Radiation Pattern; Fasad Array Antenn; Vivaldi Antenn; Skanningsförlust; Täckningsvinkel; Sub-array; Inbyggt strålmönster;

    Abstract : Phased array antennas with small size and light weight are proposed to make signal transmitting more efficiently and accurately. These antennas have such advantages that they can realize beam scanning over a large range, accurately track and identify targets within the observation range. READ MORE

  4. 3. Dual-polarized fully-metallic Vivaldi antenna array in a triangular lattice

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

    Author : Omar Orgeira Alvarez; [2022]
    Keywords : Base station; Mobile communications; Phased arrays; Vivaldi antenna; Stripline; Basstation; Mobilkommunikation; Phased arrays; Vivaldi-antenn; Stripline;

    Abstract : New mobile communication generations need electromagnetic sensors capable of steering their high-directive beams towards the users. Conventional base stations use square lattice phased arrays to accomplish this task. These arrays are composed of a large number of radiating elements to achieve the required high directivity and scanning capabilities. READ MORE

  5. 4. Design and Test of: Wide Band and Highly Polarized Antenna for 60GHz

    University essay from Uppsala universitet/Institutionen för teknikvetenskaper

    Author : David Larsson; [2017]
    Keywords : antenna; microwaves; millimetre wave; 60 GHz;

    Abstract : In this work  high gain antennas are investigated for the 60 GHz frequency. The goal is to produce a high bandwidth point-to-point wireless network that could enable improved and new features in embedded systems used to detect particles in high energy physics. A literature study was performed aiming at simple, high gain, highly polarised antennas. READ MORE
