  1. 21. A Cost-Effective Luneburg Lens Based on Glide-Symmetric Metasurface for 5G Applications

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

    Author : Martin Mattsson; [2018]
    Keywords : ;

    Abstract : In this work, a cost-eective at Luneburg lens antenna operating at the Ka-band is presented.The antenna is suitable for high frequency applications in future communicationnetworks such as 5G systems due to its simple feeding, high directivity, and low loss.The lens is composed of a parallel plate structure loaded with glide-symmetric holes.

  3. 22. Design and Test of: Wide Band and Highly Polarized Antenna for 60GHz

    University essay from Uppsala universitet/Institutionen för teknikvetenskaper

    Author : David Larsson; [2017]
    Keywords : antenna; microwaves; millimetre wave; 60 GHz;

    Abstract : In this work  high gain antennas are investigated for the 60 GHz frequency. The goal is to produce a high bandwidth point-to-point wireless network that could enable improved and new features in embedded systems used to detect particles in high energy physics. A literature study was performed aiming at simple, high gain, highly polarised antennas. READ MORE

  4. 23. Investigation and comparison between radiation and phase center for canonical antennas

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

    Author : Casimir Ehrenborg; [2014]
    Keywords : Technology and Engineering;

    Abstract : The phase center is defined as the point on an antenna from which the far field radiation seems to originate. Phase center calculations are often uncertain and vague, and very little concrete information is available on the subject. Recently, a replacement parameter called the radiation center was introduced in [5]. READ MORE

  5. 24. Planar Antennas for Terahertz Detectors

    University essay from Avdelningen för elektronik, matematik och naturvetenskap

    Author : Zakir Hossain; [2012]
    Keywords : ;

    Abstract : The use of the millimeter-wave and terahertz (THz) systems are becoming very important in various scientific and military applications. In many applications i.e. radio-astronomy, THz imaging, remote sensing, secure communication links, THz radars, plasma diagnostics etc. READ MORE
