  1. 1. A Novel and an Efficient Design of an Inverted F-Antenna for Bluetooth Low Energy Communications

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi

    Author : Amer Khatib; [2019]
    Keywords : Antenna; Communication; design; testing; Wireless communications; bluetooth.;

    Abstract : Constantly, antenna plays an important role in expanding the wireless communication systems in different technology applications for example, but not limited to, IoT communications and automotive radar systems. On the other hand, the Bluetooth-Low-Energy (BLE) benefits different sorts of applications, as it offers (i) a very low power consumption, (ii) a very fast data transfer, (iii) and an inexpensive/efficient solution as well.

  3. 2. Helical Waveguides With Higher Symmetries

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

    Author : Mikko Kjellberg; Johan Lundgren; [2018]
    Keywords : ;

    Abstract : Helical waveguides are widely used today as slow wave structures and as normal or axial mode antennas. By introducing higher symmetries in the structure the dispersive properties of the waveguide can be manipulated and the helices can be made to radiate energy as leaky wave antennas. READ MORE

  4. 3. Antenna for GNSS Reception in GEO-Orbit

    University essay from KTH/Rymd- och plasmafysik

    Author : Patrick Magnusson; [2014]
    Keywords : GNSS antenna; GNSS; GPS; antenna; GEO; helical antenna; circular array; conical;

    Abstract : There are a number of global navigation satellite systems (GNSS), in use or planed, which are used for navigation on earth but also for autonomous navigation of satellites in low earth orbit (LEO). It would be desirable to also have autonomous navigation in geosynchronous earth orbit (GEO) to reduce costs and make it possible to get higher accuracy on the position of the satellite. READ MORE

  5. 4. Interference and Energy Conservation in Phased Antenna Arrays and Young’s Double Slit  Experiment

    University essay from Institutet för rymdfysik, Uppsalaavdelningen; Institutionen för fysik och astronomi

    Author : Andreas Lundin; [2012]
    Keywords : Interference; energy conservation; double slit; antenna; antennas; array; phased; electromagnetic coupling;

    Abstract : The interest in creating and detecting electromagnetic waves carryingangular momentum in such a way that they form helical wavefronts,so called "twisted light'', has increased in recent decades.One possible way of generating such waves at radio frequenciesis to use a circular phased antenna array, where a larger relativephasing of the antenna elements corresponds to more twist of thewavefront per wavelength.
