1. 1. Design of a grating lobe mitigated antenna array architecture integrated with low loss PCB filtering structures

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

   Author : Eduardo Salvador Lopez; [2023]
   Keywords : Band-pass filters; Beam forming networks; Irregular subarrays; Particle Swarm Optimization; PCB; Penrose tessellation; Planar phased arrays; Quantization lobes; Scanning; Suspended stripline; Bandpassfilter; lobformning; matningsnätverk; Irreguljära gruppantenner; Particle Swarm Optimization; PCB; Penrose tessellation; Plana fasade gruppantenner; sidlober; Utstyrningsvinkel; Suspended stripline;

   Abstract : Massive multiple input multiple output - MIMO systems are a reality and modern communication systems rely upon this technology to cope with the increasing need for capacity and network usage. Antenna arrays are at the heart of the of the massive-MIMO system and are the enabling technology. READ MORE

3. 2. Scann Loss Reduction on Phased Array Antenna

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

   Author : Wanyu Zhang; [2022]
   Keywords : Phased Array Antenna; Vivaldi Antenna; Scan Loss; Coverage Angle; Sub-array; Embedded Radiation Pattern; Fasad Array Antenn; Vivaldi Antenn; Skanningsförlust; Täckningsvinkel; Sub-array; Inbyggt strålmönster;

   Abstract : Phased array antennas with small size and light weight are proposed to make signal transmitting more efficiently and accurately. These antennas have such advantages that they can realize beam scanning over a large range, accurately track and identify targets within the observation range. READ MORE

4. 3. Design of a Leaky-wave Antenna Based on Goubau Line for Imaging Applications

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

   Author : Roger Bock Filella; [2022]
   Keywords : leaky-wave antenna; radar systems; Goubau Line; glide symmetry; dispersion diagram; endfire; broadside;

   Abstract : The project main purpose is to design a prototypeof a leaky-wave antenna (LWA) which will serve as a basisto future manufacturing of a more advanced product withpotential use for an imaging radar system. The antenna consistsof Goubau line corrugations with rectangular radiation patches. 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. Millimeter-Wave Pencil Beam Leaky-Wave Antenna

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

   Author : Tom Eriksson; Erik Westberg; [2021]
   Keywords : Leaky-wave antenna LWA ; Continuous transverse stubs CTS ; Parallel plate waveguide PPW ; Dispersion;

   Abstract : Moving into higher frequencies, in occurrence withmodern applications, poses the issue of higher attenuation ofelectromagnetic waves, which in turn demand more directiveantennas. This paper proposes a directive antenna designoperating at 30GHz based on leaky-wave technology. Themodel consists of two main components. READ MORE
