  1. 6. The measurement of antenna VSWR by means of a Vector Network Analyzer

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

    Author : LIUJING YANG; [2020]
    Keywords : Vector Network Analyzer VNA ; Open kit; Short kit; Load kit; VSWR; 𝑆11; Smith chart; reflection coefficient;

    Abstract : The VSWR is an important entity when assessing the properties of an antenna. This report presents measurements of the VSWR, related to antennas, by means of a Vector Network Analyzer. The open/short/load calibration method is used as a preparation before the actual measurement in order to obtain accurate results. READ MORE

  3. 7. Design, Construct and Test of Ultra-Wide Band Triple-layer Meta-material Absorber

    University essay from Högskolan i Gävle/Elektronik

    Author : Pu Sun; [2016]
    Keywords : ;

    Abstract : In this paper, the design, simulation, fabrication and measurement of an ultra-wideband (UWB) meta-material absorber (MMA) is presented. The proposed MMA is planned to place between transmitter antenna and receiver antenna in a radar detection system in order to reduce the crosstalk. READ MORE

    University essay from Avdelningen för elektronik, matematik och naturvetenskap

    Author : Sergio Apicella Fernández; [2014]
    Keywords : ;

    Abstract : The dielectric properties determine the electrical characteristics of materials. These properties are important for understanding the behavior of materials and how they can interact with each other. READ MORE

  5. 9. Development of a GB-SAR System and Perform Basic and Advance Measurements for a Fixed Target

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Mohammed Faisal; [2011]
    Keywords : Double Ridge Guide Horn Antenna; Global Backprojection GBP ; Ground-Based SAR GB-SAR ; Interferometry; Low loss-high frequency cable; Vector Network Analyzer VNA .;

    Abstract : Ground-Based Synthetic Aperture Radar (GB-SAR) system is a new innovative monitoring technique has been invented depending on the use of ground based applications and highly repeatable measurements. GB-SAR is a new class of SAR system based on unconventional platform like ground, building and ground vehicles that acts as a useful complement of airborne and spaceborne SAR system. READ MORE

  6. 10. Use SNA instead of VNA to characterize indoor channel : implementing and rms theory

    University essay from Avdelningen för elektronik, matematik och naturvetenskap

    Author : Jingou Lai; Che Liu; [2010]
    Keywords : network analyzer; rms delay; hilbert transform;

    Abstract : In this report we focus on the use of an economical way on how Scalar Network Analyzer (SNA) works instead of Vector Network Analyzer (VNA) to estimate the phase angle of signals in indoor channel. This is detailed in RMS delay theory and simulation section, experimental is designed in the according Experiment Design section, where we also state the required measurements known from the math part.
