  2. 1. Studies of Three Different Methods to Estimate the Up-link Performance of Mobile Phone Antennas

    Author : Sathyaveer Prasad; Peter Händel; Claes Beckman; Jan Carlsson; Högskolan i Gävle; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Antenna measurements; mobile phones; total radiated power; reverberation chamber; anechoic chamber; Telia Scattered Field Method; Maximum likelihood Estimator; Telecommunication; Telekommunikation;

    Abstract : Antennas play an important role in determining the overall radio performance for wireless communications. If all other radio components perform according to their specifications, the performance of a mobile phone can be entirely determined by measuring the efficiency of its antenna. READ MORE

  4. 2. Reverberation Chamber Characterizations for Passive and Active OTA Measurements

    Author : Chen Xiaoming; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Reverberation chamber (RC) has drawn more and more attention as a multipath emulator over the past decade. It has been used for antenna efficiency measurements. It has also been used to measure diversity gain and multi-input multi-output (MIMO) capacity using multi-port antenna. READ MORE

  5. 3. Embedded Element Patterns in Combination with Circuit Simulations for Multi-Port Antenna Analysis

    Author : Kristian Karlsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; antenna efficiency; Greens function; multi-port antenna; impedance matching; reverberation chamber; correlation; antenna arrays; Embedded element pattern; optimization; antenna diversity;

    Abstract : This thesis is a result from work on two different subjects, electromagnetic simulations of reverberation chambers and a methodology for the analysis of multi-port antennas. The subjects can be linked together by their contribution to knowledge in electromagnetic simulations and characterization of antennas. READ MORE
