  1. 1. Ray-Tracing Modeling of Grating Lobe Level Reduction by Using a Dielectric Dome Antenna

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

    Author : Lukas Jonasson; [2023]
    Keywords : Array antenna; Dielectric dome; Ray-Tracing; Grating lobe; Particle Swarm optimization; Gruppantenn; Dielektrisk kupol; Strålspårning; Gallerlob; Particle Swarm optimering;

    Abstract : With the newly deployed fifth-generation telecommunications system and upcoming sixth-generation, high-gain antennas with hemispherical scanning capabilities are of high interest. Phased array antennas allow for fast scanning capabilities with electronic beam-steering. READ MORE

  3. 2. Ray Tracing Algorithm for Dielectric Domes

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

    Author : Maria Pubill; [2023]
    Keywords : Array antenna; dielectric dome; Ray-Tracing; reflection; absorption losses; matching layers; Arrayantenn; dielektrisk kupol; strålföljning; reflektion; absorptionsförluster; anpassningsskikt;

    Abstract : Almost hemispherical scanning capabilities are required for modern wireless communication systems to produce broad coverage without performance degradation. Phased array antennas are commonly used as a fully-electronic beam-steering solution for its rapidity in beam switching. READ MORE

  4. 3. Design of a Dielectric Radome using a Ray-Tracing Model for Satellite Communications

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

    Author : Flores Espinosa Núria; [2023]
    Keywords : Dielectric radome; Ray tracing; Array antenna; Lens antenna; Satellite communications; Radom dielèctric; Traçat de Rajos; Arranjament d’antenes; Antena de lent; Comunicacions per satèl·lit; Dielektrisk radome; Strålspårning; Gruppantenn; Linsantenn; Satellitkommunikation;

    Abstract : In recent years, there has been a huge increase in the use of satellite communications. This has led to a need for more capacity, which can be solved by moving towards higher frequency bands in search of higher bandwidths. READ MORE

  5. 4. Scanning range extension by combining arrays with lenses

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

    Author : Hairu Wang; [2022]
    Keywords : Dome Antenna; Dielectric Lens; Array Antenna; Kupolantenn; Dielektrisk lins; Array antenn;

    Abstract : Array antennas, and more specifically phased array antennas, are widely used in radar detection and communication systems because of their excellent beam scanning ability and simple control. Generally speaking, the scanning function can be realized in two ways: mechanically or electronically. READ MORE

  6. 5. Geodesic Lens Antenna for sub-THz Imaging

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

    Author : Joan Mitjans i Blasco; [2021]
    Keywords : ;

    Abstract : The Millimiter Wave (mmW) frequency band, characterized by a high atmospheric attenuation and wide available bandwidth has become of big interest for high accuracy radar imaging applications. The continuous development of the Monolithic Microwave Integrated Circuit (MMIC) technology yields to the appearance of different commercial-off-the-shelf (COTS) radar transceivers at that frequency band, where the antennas are fully integrated into the chip.
