1. 6. 3D Printing a Maxwell Fish Eye Lens With Periodic Structures

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

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

   Abstract : 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. READ MORE

5. 9. Design of Dual Band Patch Antenna Array

   University essay from Fysik och elektroteknik; Tekniska högskolan

   Author : Haji Akbar Babar; Atif Khattak; [2012]
   Keywords : ;

   Abstract : Low profile antennas are very useful in applications such as missile, aircraft, cellular applications and satellites, because in these types of applications, some commonly important constraints are cost, size, weight, performance and easy installation. Microstrip patch antenna fits quite comfortably in this category. READ MORE

6. 10. S-Band Antenna Array

   University essay from Institutionen för fysik och astronomi

   Author : Mathias Dalevi; [2010]
