  1. 6. Study of different methodologies to determine relative dielectric constant of given substrate using fabrication, modelling and measurement strategies

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Anders Lundberg; [2021]
    Keywords : Relative dielectric constant; relative permittivity; PCB substrate material;

    Abstract : In this thesis, different methods for measuring the relative dielectric constant is investigated using simulations and experimental approaches. The first method is known as the S-parameter inversion method. In this method formulae is used to calculate the characteristic impedance of the microstrip line from measured S-parameters. READ MORE

  3. 7. Design of 5G antenna arrays based on Multi-directivity

    University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Author : Zhiwei Wang; Shen Zhang; [2020]
    Keywords : 5G; antenna array; microstrip; feed network;

    Abstract : As communication technology evolves, the focus shifts to 5G. The discussion of 5G cannot be separated from a discussion of related antenna systems. Chapter 1 is a brief introduction to our work, which is an antenna array for a 5G communication system operating in the band 3.4 to 3. READ MORE

  4. 8. Design and Implementation of a Multipurpose Radar Sensor

    University essay from Linköpings universitet/Fysik och elektroteknik; Linköpings universitet/Tekniska fakulteten

    Author : Johan Niklasson; Axel Åström; [2019]
    Keywords : Radar; FMCW; CW; DoA; Doppler-radar; Sensor; DSP; CMSIS; HAL; STM32; ARM; Microwave; HF; six-port;

    Abstract : This thesis presents the design and implementation of a multifunctional radar sensor. Utilising microstrip transmission line technology, a front-end receiver has been designed based upon a six-port architecture. READ MORE

  5. 9. Study of the effects of applying higher symmetries to printed filters

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

    Author : Jose Luis Medran del Rio; [2018]
    Keywords : Glide symmetry; printed filter; microstrip; higher symmetries; Glidsymmetri; tryckta filter; mikrostrip; högre symmetrier;

    Abstract : In recent years, a new field of study has arisen around theapplication of the so-called higher symmetries to structures that werealready thought to be completely studied and with no room forimprovement in terms of benefits.There are two types of higher symmetries, named glide and twistsymmetries.

  6. 10. Compact & Lightweight Antenna Designs for Harmonic Radar Application

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

    Author : Ze Fu; Hamza Bin Faheem; [2018]
    Keywords : Harmonic Radar; microstrip patch antenna array; 9.41GHz; 18.82GHz; Technology and Engineering;

    Abstract : The purpose of this paper is to design a new lightweight and compact antenna system for harmonic radar applications to be used to trace the migration of the Bogong moths. The main approach adopted in this paper to solve this problem is to build three antennas suitable for use in the real environment, where the modeling and the simulations were done in CST Microwave Studio Suite 2018.
