  1. 1. Wideband Dielectric Resonator Antenna Array for Autonomous Vehicles

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi

    Author : Andreas Johansson; Luke Müller; [2023]
    Keywords : DRA; dielectric resonator antenna; 5G; FR2; 28GHz; NR; antenna; circular polarization; autonomous vehicles;

    Abstract : With the rapid advancement of autonomous vehicles, reliable and efficient wireless communication systems with high data rates have become essential for their safe and efficient operation and further evolution. High data rates are found in the higher frequency bands where conductive antennas lack radiation efficiency. READ MORE

  3. 2. 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

  4. 3. Portable HF Antennas for Concurrent Multiband Systems

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

    Author : Sambhav Malhotra; [2022]
    Keywords : Antenna; HF; Skywave Propogation; Multiband;

    Abstract : Current HF communication systems are confined to transmit in relatively narrow frequency band of a few 100 kHz at the time. The problems with limited bandwidth accumulate in HF-networks with multiple links and such networks are therefore hardly “internet capable” today. READ MORE

  5. 4. 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

  6. 5. Design of Cellular and GNSS Antenna for IoT Edge Device

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi

    Author : Ioannis Broumas; [2019]
    Keywords : IoT; Internet of Things; Edge device; LTE; 4G; LTE-M1; Antenna; Antenna System; Narrow Band IoT; NB-IoT; Plannar Antennas; GPS; PCB; multiband antenna;

    Abstract : Antennas are one of the most sensitive elements in any wireless communication equipment. Designing small-profile, multiband and wideband internal antennas with a simple structure has become a necessary challenge. READ MORE
