1. 1. Validation of Quasi-Optical Antireflective Structures for Radar Lenses through Experimentation and Simulation

   University essay from Högskolan i Halmstad/Akademin för informationsteknologi

   Author : Jeslin Preetha Sam Oliver; Simbarashe Tongai Makonese; [2023]
   Keywords : ;

   Abstract : This study focuses on designing, developing, and testing 3D-printed radar lenses with varying heights of Anti-Reflective (AR) structures (0.75mm, 1mm and 1.25mm). Radar lenses are essential to improve signal transmission and reception for radar systems. READ MORE

3. 2. Anti-Reflective Coatings for 3D Printed Quasi-Optical Lenses: Experiments, Simulations, Verification, and Optimization

   University essay from Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

   Author : Christina Ashok; [2022]
   Keywords : ;

   Abstract : This thesis aims to see how well anti-reflective coatings created for dense material millimeter wave integrated lens work and to validate observations using electromagnetic simulation. The dielectric material was chosen for lens fabrication because it allows for high power transfer capability via the lens and allows the production of affordable and compact-size lenses. READ MORE

4. 3. Non-Planar 3D Printed Radar Lenses

   University essay from Högskolan i Halmstad/Akademin för informationsteknologi

   Author : Ali Bukht; [2021]
   Keywords : Non-Planar; 3D Printed; Lenses; Slic3r; 60 GHz;

   Abstract : The primary motivation behind this research was to determine whether 3D printed lenses printed out using the non-planar technique can help achieve better beam intensity for a 60 GHz printed-circuit-board based radar and consequently improve radar efficiency. Non-planar printing is a new development in the 3D printing industry. READ MORE

5. 4. 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
