1. 1. Design of a Maxwell Fish-Eye Lens in PCB Technology With a Glide-Symmetric Metasurface

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

   Författare :Philip Arnberg; Oscar Barreira Petersson; [2019]
   Nyckelord :Maxwell fish-eye lens; unit cell; metasurface; glide symmetry.;

   Sammanfattning : The aim of this project is to design a cost-effective planar Maxwell fish-eye lens in PCB technology operating at the center frequency 5 GHz with a bandwidth of 20 %. An approach to design a cost-effective lens is to use a metasurface, which is commonly realized as a periodic structure of unit cells. LÄS MER

3. 2. 3D Printing a Maxwell Fish Eye Lens With Periodic Structures

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

   Författare :Valentine Lin; Tarek Sayed Hamad; [2019]
   Nyckelord :Maxwell fish eye lens; dielectric lens antenna; metamaterial; periodic structure; 3D printed lenses.;

   Sammanfattning : With the rise of high frequency communication systems such as 5G, new types of antennas has to be developed in order to meet the new requirements. In recent years, lens antennas made of periodic structures has been shown to have desirable performance when increasing operational frequency without increasing the size of the antennas. LÄS MER
