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

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

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

   Sammanfattning : 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. LÄS MER

3. 2. Ray Tracing Algorithm for Dielectric Domes

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

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

   Sammanfattning : 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. LÄS MER

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

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

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

   Sammanfattning : 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. LÄS MER
