  1. 1. Far-field pattern synthesis of transmitarray antennas using convex optimization techniques

    University essay from KTH/Tillämpad fysik

    Author : Marie Defives; [2022]
    Keywords : Applied physics; Transmitarray antennas; convex optimization; Tillämpad fysik; Transmitarray-antenner; konvex optimering;

    Abstract : Transmitarrays antennas (TAs) can be seen as the planar counterpart of optical lenses. They are composed of thin radiating elements (unit cells) which introduce different local phase shifts on an incident electromagnetic wave, emitted by a primary source, and re-radiate it. READ MORE

  3. 2. Restrictions in the far-field of antennas enclosed in bodies of revolution

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Clara Bäck; [2016]
    Keywords : Antenna pattern synthesis; body of revolution; far-field restrictions; genetic algorithm; Technology and Engineering;

    Abstract : Antennas can be found everywhere in our everyday life. One of the applications for them are space satellites, which can be used for communication, positioning and weather supervision. A satellite carries several components on its body, such as solar panels and cameras, therefore there is a volume restriction for the antenna to fit. READ MORE

  4. 3. Maximum Capacity Antenna Design for an Indoor MIMO UWB Communication System

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Ran Liu; Hao Liu; [2012]
    Keywords : MIMO; UWB; Antenna Design; In-door Communication and Capacity Analysis;

    Abstract : Ultra-wideband (UWB) offers a high data rate transmission, however it only can be used in short distance communication due to its low power restricted by regulations, therefore it is applicable for an indoor scenario. Within an enclosed (indoor) scenario, there exist many possible multipaths of electromagnetic waves which lead to an effect known as fading [Big07]. READ MORE

  5. 4. Approximation of Antenna Patterns With Gaussian Beams in Wave Propagation Models.

    University essay from Institutionen för datavetenskap, fysik och matematik, DFM

    Author : Navid Sherkat; [2011]
    Keywords : Gaussian beam; Pattern synthesis; Point matching; Wave propagation models;

    Abstract : The topic of antenna pattern synthesis, in the context of beam shaping, is considered. One approach to this problem is to use the method of point matching. This method can be used to approximate antenna patterns with a set of uniformly spaced sources with suitable directivities. READ MORE
